Machine learning models are one of the major contributors to the advancement of artificial intelligence technologies. By enabling systems to learn from data and predict outcomes with utmost accuracy, these models have become crucial for organizational growth. Machine learning models are critical in automating decision-making and enhancing predictive analytics.

These models serve as mathematical frameworks that help computers interpret complex datasets and identify patterns that would be difficult to recognize. By leveraging ML models, your organization can adapt to changing scenarios and make decisions based on data rather than intuition.

This guide offers insights into what machine learning models are, including their types, benefits, and use cases.

What are Machine Learning Models?

Machine learning (ML) models are a type of mathematical model designed to learn from data through specific algorithms. You can train the model by providing it with data and applying an algorithm that enables it to reason and detect relationships within the data.

After the initial training phase, you test the model using new unseen data to evaluate its performance. This evaluation phase tells you how well the ML model generalizes its knowledge to new scenarios, helping adjust the parameters to improve its accuracy.

For example, let’s say you want to build an application that recognizes user emotions based on their facial expressions. You can start by training a model with images of faces, each labeled with an emotion, such as happy, sad, angry, or crying. Through training, the model will learn to associate specific facial features with these emotions. You can then evaluate its performance to see if it predicts emotions accurately and identify any areas that need further refinement. After thorough evaluation and adjustment, you can use this model for your application.

What are Different Types of Machine Learning Models

There are many different types of machine learning models that can be classified into two different categories based on how they are trained.

Supervised Learning

In supervised learning, you train the model on labeled data, which is the data annotated with known outputs (labels). The model is provided with both the input and its corresponding output dataset. In the training phase, the model learns about different relationships between the input and output, minimizing the error in its predictions. Once the training is complete, you can evaluate the model using new data (testing dataset) to see how accurately it predicts the output.

Here are the two different types of supervised learning models:

Regression Model

Regression in supervised learning is used to analyze the relationship between a dependent variable (what you want to predict) and an independent variable (factors influencing the prediction). The main objective is to find how any changes in an independent variable affects the dependent variable.

For example, if you are predicting a house’s price based on factors like location and size, the regression model helps you establish a relationship between these factors and price. The relationship will help you quantify how much each factor contributes to the price. This model is mainly used when the output is a continuous value.

Terminologies you need to understand 

• Response Variable: Also known as the dependent variable, it is the primary factor that you want to predict.

• Predictor Variable: Also known as the independent variable, it is the variable used to predict the response variable. 

• Outliers: Outlier data points significantly differ from the other points in a dataset. Their values are either too high or low compared to other points. Because of the difference, the analysis can get skewed and lead to inaccurate results, so outliers need to be handled carefully.

• Multicollinearity: Multicollinearity occurs when there is a high correlation among the independent variables. For example, when predicting house prices, the number of rooms and square footage as independent variables might be correlated since larger houses tend to have more rooms. The correlation makes it difficult for the model to determine the individual effect of each variable on the price.

Types of Regression Model 

• Linear Regression: This is the simplest form of regression, where the relationship between the input and output variable is assumed to be linear. The value of the dependent variable changes linearly with the independent variable, making a straight line.

The relationship can be defined using the following equation: 

 Y= bX+c

In the above equation:

• Y is a dependent variable
• X is the independent variable
• b is the slope indicating the change
• c is the intercept that defines the value of Y when X=0.

For example, if you are predicting the salary of an individual based on experience, then the variable for salary is dependent; the salary increases with the increase in experience.

• Polynomial Regression: Polynomial regression defines the relationship between input and output variables by an n-degree polynomial equation. This model is used to capture more complex patterns that don’t fit a straight line. The additional terms allow the model to capture intricate relationships among variables, making it capable of fitting to curves or other complex patterns.

A polynomial equation might look like this: 

Here,

• y is dependent
• x is independent
• b₀, b₁, etc., are coefficients that the model learns

• An example of polynomial regression is if you want to predict a salary based on years of experience. At first, the salary may increase with years, but after reaching a certain level, the salary factor may slow down or plateau.

Classification Model

Classification in supervised learning is used to categorize new data into predefined categories based on the training dataset the model has been previously exposed to. The model learns from labeled data, where each data point is associated with its corresponding label.

Once the training is complete, the model can be tested on new data to predict which category it belongs to. For example, a category may include binary outcomes like Yes or No, 1 0r 0, as well as multi-class outcomes like Cat, Dog, Fruit, or Animal.

In classification models, a function maps the input variable to discrete outputs. The function can be represented mathematically as:

y = f(x)

Here:

• y denotes the output
• f is the function
• x represents the features of the input variable

Types of Classification Models

• Logistic Regression: This is the type of model that is used for binary classification tasks. You can optimize this model to predict the categorical variables where output is either Yes or No, 1 or 0, True or False, etc. For example, this model can be used in spam email detection, where it classifies incoming emails as either spam (1)  or not spam (0).

• Support Vector Machine (SVM): The SVM model helps to find the hyperplane that separates data points of one class from another in high-dimensional space.

A hyperplane can be defined as a decision boundary that maximizes the margin between the nearest points of each class. The data points closest to the hyperplane are support vectors, which are crucial for defining the hyperplane. SVM focuses on the support vectors rather than all data points to make predictions.

Unsupervised Learning

In unsupervised learning algorithms, the model is trained on unlabeled data; there are no predefined labels or outputs. The main objective of the model is to identify patterns and relationships within the data. It works by learning from the inherent features of the data without the need for external guidance or supervision.

The main types of unsupervised learning models include:

• Clustering: It is the type of unsupervised learning where the model groups data points based on their similarities. The model forms homogeneous groups from a heterogeneous dataset using similarity metrics like cosine similarity. For instance, you can apply clustering to enhance customer segmentation, grouping customers with similar purchasing habits. 

• Association: Association is a rule-based approach that identifies relationships or patterns among various items of large datasets. It works by finding frequent itemsets and drawing inferences about associations between them. For example, an association model can be used to analyze customer purchasing patterns. The model can help you identify that customers who buy bread are likely also to purchase butter. This insight can be useful for building useful product placement strategies.

Decision Tree Model of Machine Learning

Decision tree is a predictive approach to machine learning. It operates by repeatedly splitting the dataset into branches or segments based on specific conditions in the input data. Each split helps to separate data with similar characters, forming a structure that resembles a tree. 

Structure of a Decision Tree

• Root Node: It represents the entire dataset and initiates the decision-making process.
• Internal Node: An internal node represents a decision point where the data is split further based on attributes.
• Branch: Each branch represents the outcome of a decision and the path that leads from one decision to another.
• Leaf Nodes: These are the endpoints or terminal nodes of the tree where the final prediction is made.

How Does a Decision Tree Work?

A decision tree works by breaking down a dataset into smaller subsets based on some specific conditions (questions) about input features. At each step, the data is split, and similar outcomes are grouped. The process continues until the dataset can’t be split further, reaching the leaf nodes (where final predictions are made).

Reinforcement Machine Learning Model 

A reinforcement learning (RL) model is a type of machine learning model that enables a computer system to make decisions to achieve the best possible outcomes. In this model, an agent learns to make a decision by interacting with the environment. The agent takes actions to achieve a goal and receives feedback in the form of rewards or penalties based on the actions. RL model’s main objective is to learn how to maximize the cumulative reward over time. 

For example, you can optimize your pricing strategy using RL machine learning models based on customer behavior and market conditions.

• Agent: The pricing algorithm acts as the agent, helping make real-time decisions about product pricing.
• Environment: The market landscape, including customer demand, sales data, and competitor price, represents the environment.
• Action: The agent can set various price points, increasing or decreasing, or maintaining the current price.
• State: It includes factors such as current demand, inventory levels, and customer engagement metrics.
• Rewards: The agent can receive a positive reward for increased sales or a negative reward for decreased sales.

After a few iterations, you learn about customer buying patterns and can identify the optimal pricing strategy that maximizes revenue while remaining competitive.

Practical Use Cases of Machine Learning Models

The following are some practical examples that demonstrate the impactful use of machine learning in various applications across different industries.

Recommendation Systems

Many big retailers, such as Amazon and Flipkart, or streaming platforms like Netflix, use ML-powered recommendation systems to analyze users’ preferences and behavior. Through content-based filtering, these systems aim to enhance customer satisfaction and enhance engagement by providing relevant product or service suggestions.

For example, let’s take a look at how Netflix recommends movies or shows. It uses ML recommendation systems to analyze what shows you have watched, how long you have watched them, and what you have skipped. The system learns your habits and finds patterns in the data to suggest content you will likely enjoy, and that perfectly aligns with your taste. 

Spam Email Filtering

Email services need robust systems to protect users from spam and phishing attacks. A reliable filtering system can be built using machine learning to sort relevant emails from unwanted or harmful content. The ML model analyzes each email’s content, such as sender’s location, email structure, and IP address. It learns from millions of emails to detect subtle signs of spam that may be missed by rule-based systems.

For example, Google employs machine learning powered by user feedback to catch spam and identify patterns in large datasets to adapt to evolving spam tactics. The Google ML model has advanced to a point where it can detect and filter spam with about 99% accuracy. It uses a variety of AI filters that determine what mail is spam. These filters look at email characteristics like IP address, domain and subdomains, and bulk sender authentication. The ML model also optimizes user feedback to improve the filtering process, where it learns from patterns like when a user marks spam for a certain email in their inbox.

Healthcare Advancements

Machine learning models can help analyze complex medical data such as images, patient histories, and genetic information. This can facilitate early disease detection, enabling timely medical interventions.

For example, machine learning models can help healthcare providers detect early signs of cancer in medical images like MRIs and CT scans. These models help to identify minute details and anomalies in the images that the naked eye can overlook. The more accurate the detection, the more accurate the diagnosis.

Predictive Text

Predictive text technology enhances typing efficiency by suggesting the next word or phrase likely to be used. ML models learn from language patterns and previous inputs to predict what users will type, improving the speed and accuracy of suggestions.

For example, Google’s smart compose in Gmail is powered by machine learning, which helps you write emails faster; it offers suggestions as you enter text. The smart compose is available in English, Spanish, French, Italian, and Portuguese.

Here’s a graph that showcases the popularity of neural networks over the past year based on the number of Google searches.

You can see a constant interest of people in the concept of neural networks.

This guide highlights the concept of machine learning neural networks and their working principles. It also demonstrates how to train a model and explores use cases that can help you understand how they contribute to better data modeling.

What Are Machine Learning Neural Networks?

A neural network is a type of machine-learning model developed to recognize patterns in data and make predictions. The term “neural” refers to neurons in the human brain, which was an early inspiration for developing these systems. However, neural networks cannot be directly compared with the human brain, which is too complex to model.

Neural networks consist of layers of nodes, or neurons, each connected to others. A node activates when its output is beyond a specified threshold value. Activation of a node signifies that it can send data to subsequent nodes in the next layer. This is the underlying process of neural networks, which are trained using large datasets to improve their ability to respond and adapt. After training, they can be used to predict outcomes for previously unseen data, making them robust machine learning algorithms.

Often, neural networks are referred to as black boxes because it is difficult to understand the exact internal mechanisms they use to arrive at conclusions.

Components of Neural Network

To understand the working process of a machine learning artificial neural network, you must first learn about weights, biases, and activation functions. These elements determine the network’s output.

For example, to perform a linear operation with two features, x₁ and x₂, the equation  “y = m₁x₁ + m₂x₂ + c” would be handy.

Weights: These are the parameters that specify the importance of a variable. In the sample equation, m₁ and m₂ are the weights of x₁ and x₂, respectively. But how do these weights affect the model? The response of the neural network depends on the weights of each feature. If m₁ >> m₂, the influence of x₂ on the output becomes negligible and vice versa. As a result, the weights determine the model’s behavior and reliance on specific features.

Biases: The biases are constants, like “c” in the above example, that work as additional parameters alongside weights. These constants shift the input of the activation function to adjust the output. Offsetting the results by adding the biases enables neural networks to adjust the activation function to fit the data better.

Activation Function: The activation functions are the central component of neural network logic. These functions take the input provided, apply a function, and produce an output. The activation function is like a node through which the weighted input and biases pass to generate output signals. In the above example, the dependent variable “y” is the activation function.

For real-world applications, three of the most widely used activation functions are:

• ReLU: Rectified Linear Unit, or ReLU, is a piecewise linear function that returns the input directly if its value is positive; if not, it outputs zero.
• Sigmoid: The sigmoid function is a special form of logistic function that outputs a value between 0 and 1 for all values in the domain.
• Softmax: The softmax function is an extension of the sigmoid function that is useful for managing multi-class classification problems.

How Do Neural Networks Work?

A neural network operates based on the architecture you define. The architecture comprises multiple layers, including an input layer, one or more hidden layers, and an output layer. These layers work together to create an adaptive system, enabling your model to learn from data and improve its prediction over time.

Let’s discuss the role of each layer and the working process of a machine learning artificial neural network.

Input Layer: The input layer represents the initial point of data entry in the neural network; it receives the raw data. Each node in the input layer defines a unique feature in the dataset. The input layer also organizes and prepares the data so that it matches the expected input format for further processing by subsequent layers.

Hidden Layer: The hidden layers contain the logic of the neural network with several nodes that have an activation function associated with them. These activation functions determine whether and to what extent a signal should continue through the network. The processed information from the input layer is transformed within the hidden layers, creating new representations that capture the underlying data patterns.

Output Layer: The output layer is the final layer of the neural network that represents the model predictions. It can have a single or multiple nodes depending on the task to be performed. For regression tasks, a single node suffices to provide a continuous output. However, for classification tasks, the output layer comprises as many nodes as there are classes. Each node represents the probability that the input data belongs to a specific class.

After the data passes through all the layers, the neural network analyzes the accuracy of the model by comparing the output with the actual results. To further optimize the performance, the neural network uses backpropagation. In backpropagation, the network adjusts the weights and biases in reverse, from the output layer back to the input layer. This helps minimize prediction errors with techniques such as gradient descent.

How to Train a Neural Network?

Let’s learn about the neural network training algorithm—backpropagation—which utilizes gradient descent to increase the accuracy of the predictions.

Gradient descent is a model optimization algorithm used in training neural networks. It aims to minimize the cost function—the difference between predicted values and actual values. The cost function defines how well the neural network is performing; a lower cost function indicates that the model is better at generalizing from the training data.

To reduce the cost function, gradient descent iteratively adjusts the model’s weights and biases. The point where the cost function reaches a minimum value represents the optimal settings for the model.

When training a neural network, data is fed through the input layer. The backpropagation algorithm determines the values of weights and biases to minimize the cost function. This ensures that the neural network is able to gradually improve its accuracy and efficiency at making predictions.

Neural networks have three types of learning: supervised, unsupervised, and reinforcement learning. While supervised learning involves training a model using labeled data, unsupervised learning involves training models on unlabeled data. In unsupervised learning, the neural network recognizes the data patterns to categorize similar data points.

On the other hand, reinforcement learning neural networks learn through interactions with the environment through trial and error. Such networks receive feedback in the form of rewards for correct actions and penalties for mistakes. The rewarding tasks are repeated while the penalties are avoided.

For instance, a robot trained to avoid fire might receive a reward for using water to extinguish the flames. However, approaching the fire without safety precautions can be considered a penalty.

What are Deep Learning Neural Networks

In deep learning neural networks, the word “deep” highlights the density of the hidden layer. Prominently known as deep learning, it is a subset of machine learning that uses neural networks with multiple hidden layers. These networks facilitate the processing of complex data by learning to extract features automatically without requiring manual feature extraction. It simplifies the analysis of unstructured data, such as text documents, images, and videos.

Machine Learning vs Neural Networks

Both machine learning and neural networks are beneficial for making predictions based on data patterns. But what factors differentiate them? In practical applications, machine learning is used for tasks such as classification and regression, employing algorithms like linear or logistic regression.

During the process of training a machine learning model, you might notice that you don’t have to manually define its architecture. Most of the machine learning algorithms come with predefined structures. This makes it fairly straightforward to apply these algorithms since they don’t require you to define the model’s architecture. Contrarily, neural networks provide you with the flexibility of defining the model architecture by outlining the layers and nodes involved. However, they lack ease of use, trading simplicity for flexibility, allowing you to build more robust models.

While machine learning effectively works with smaller or structured datasets, its performance can significantly reduce when large unstructured data is involved. Neural networks, on the other hand, are preferred for more complex situations where you want accurate modeling of large unstructured datasets.

Types of Neural Networks

Neural networks are typically categorized based on their architecture and specific applications. Let’s explore the different types of machine learning neural networks.

Feedforward Neural Network (FNN)

Feedforward neural networks are simple artificial neural networks that process data in a single direction, from the input to the output layer. Its architecture does not consist of a feedback loop, making it suitable for basic tasks such as regression analysis and pattern recognition.

Convolutional Neural Network (CNN)

Convolutional neural networks are a special type of neural network designed for processing data that has a grid-like topology, like in images. It combines convolutional layers with neurons to effectively learn the features of an image, enabling the model to recognize and classify test images.

Recurrent Neural Network (RNN)

A recurrent neural network, or RNN, is an artificial neural network that processes sequential data. It is primarily recognized for its feedback loops, which allow optimization of weights and biases to enhance output. The feedback loops enable the retention of information within the network, making RNN suitable for tasks like natural language processing and time series analysis.

• E-Vehicles: AI has become an integral part of most electronic vehicles. The underlying neural network model processes the vehicle’s sensor data in real-time to produce results, such as an object or lane detection and speed regulation. It then performs operations like steering, braking, and accelerating based on the results.

• Content Creation: The use of neural networks in content creation has been significant, with LLMs such as ChatGPT simplifying the complex tasks for content creators. To enhance creativity further, several models can create realistic video content, which you can use in marketing, entertainment, and virtual reality apps.

Key Takeaways

Understanding machine learning artificial neural networks is essential if you’re a professional working in data-driven fields. With this knowledge, you can learn about the underlying structures of most AI applications in the tech market.

Although neural networks are efficient in modeling complex data, the opacity of the hidden layers introduces a level of uncertainty. However, neural networks can effectively model data to produce accurate predictions. This makes them invaluable tools, especially in scenarios where precision is critical in AI applications.

The increasing significance of Artificial intelligence (AI) across various industries is evident from its many associated benefits. From revolutionizing marketing strategies and enhancing product innovation to improving customer satisfaction, AI is helpful with all this and more. Among the several notable applications is the integration of generative AI technologies, especially AI image generators.

Whether you’re looking for appealing visuals in marketing to drive engagement and conversion or creating targeted advertising campaigns, AI image generators are the solution.

This article discusses the details of AI image generators, the working process, and how you can build your own model. It will also highlight critical use cases, challenges, and popular image generators available on the market.

What is an AI Image Generator?

AI image generators are machine learning models that use artificial neural networks to create new images based on certain inputs. Typically, these models are trained on vast datasets of text, images, or even videos. Based on the input, the AI image generator combines various training data attributes, such as styles, concepts, and color schemes, to produce an original, context-relevant image.

The underlying training algorithm that the model uses learns about different attributes like color grading and artistic styles from the data. After training on large volumes of data, these models become efficient in generating high-quality images.

AI Image Generator Working Process

Currently, different technologies are being used to process and produce new images, including GANs, diffusion models, and Neural Style Transfer (NST). Let’s explore each to understand the working process of an AI image generator.

The Role of Natural Language Processing (NLP)

To understand text prompts, an AI image generator uses NLP, which works by transforming textual data into machine-specific language. NLP uses different methods to break down the input text into smaller segments that are then mapped in vector space. By converting text into vectors, the model can assign numerical values to complex data. The vector data can be used to accurately predict output when a new input is provided. Using NLP libraries like the Natural Language Toolkit (NLTK) allows you to convert images to AI-compatible vector formats.

Generative Adversarial Networks (GANs)

The vector produced via NLP passes through GANs—a machine learning algorithm.

GANs comprise two neural networks—a generator and a discriminator—working together to create realistic images. The generator accepts random input vectors and uses them to create fake samples.

On the other hand, the discriminator acts as a binary classifier by taking the fake samples and differentiating them from the original images. To effectively differentiate real images from fake ones, the discriminator is fed both the real and generated images during the training process.

GANs create an iterative process where the discriminator continues to find faults in the images produced by the generator, enhancing the generator’s accuracy. If the discriminator successfully classifies the generator’s output as fake, the generator undergoes upgrades to create a better image. In hindsight, if the generator’s response easily fools the discriminator, the discriminator is upgraded to identify more subtle changes in the images.

The process of creation and identification of real and fake images continues until the generator efficiently produces near-real results.

Diffusion Models

A diffusion model is a type of generative artificial intelligence. It adds noise to the original data and then tries to create new data by reversing the process or removing the noise. Commonly used diffusion processes follow a set of steps to generate new data.

In the first step, the model adds random noise to the original data via the Markov chain approach. Markov chain is a framework that defines the probability of the change in the state of a certain quantity based on its previous state. This step is also known as the forward diffusion stage.

During the training stage, the model learns how noise is added to the image and how to differentiate noisy data from the original. This step enables the model to figure out a reverse process to restore the original data.

After training, the model can remove the noise from the original data. In this stage, the model retraces its steps back to an image similar to the original. The resulting image retains some features of the input data. By following the image retrieval process, the model learns and improves its performance and finally creates new images.

Neural Style Transfer (NST)

NST is a deep learning application that combines the content of two or more images to generate a new image. Suppose you have an image to which you want to add the style of another image. To merge the characteristics of images, you can use NST.

The technique uses a pre-trained neural network that creates a new image by integrating the styles of multiple images. This process of generating a new image generally consists of two images, including the original and the style image. To understand the working mechanism of NST, you must have a basic understanding of neural networks.

The underlying principle of NST involves a neural network with different layers of neurons detecting the edges and color-grading of the image. Hidden layers of the model identify unique features like textures and shapes that are more complex to process. By passing the data through the network, NST transforms the content and style to generate a new image.

How to Build Your Own AI Image Generator App?

Artificial intelligence has been integrated into applications across diverse sectors, from automobiles to agriculture. According to the Grand View Research report, the AI market is projected to grow at a CAGR of 36.6% from 2024 to 2030. However, with the incorporation of these rapid innovations, it’s equally essential to address the safe and ethical use of AI.

This is where the need for artificial intelligence regulations comes into the picture. Without regulation, AI can lead to issues such as social discrimination, national security risks, and other significant issues. Let’s look into the details of why artificial intelligence regulations are necessary and what you need to understand about them.

Why AI Regulation is Required?

The progressively increasing use of AI in various domains globally has brought with it certain challenges. This has led to the need for regulatory frameworks. Here are some of the critical reasons why AI regulation is essential:

Threat to Data Privacy

The models and algorithms in AI applications are trained on massive datasets. These datasets contain data records consisting of personally identifiable information, biometric data, location, or financial data.

To protect such sensitive data, you can deploy data governance and security measures at the organizational level. However, these mechanisms alone cannot ensure data protection.

Setting guidelines at the regional or global level to obtain consent from people before using their data for AI purposes can ensure better data protection. This facilitates the preservation of individual rights and also establishes a common consensus among all stakeholders on using AI.

Ethical Concerns

If the training datasets of AI models contain biased or discriminatory data, it will reflect in the outcomes of AI applications. Without proper regulations, such biases can affect decisions in hiring, lending, or insurance issuance processes. The absence of guidelines for using artificial intelligence in judiciary proceedings can lead to discriminatory judgments and erosion of public trust in the law.

Regulatory frameworks compelling regular audits of AI models could be an efficient way to address ethical issues in AI. Having a benchmark for data quality and collecting data from diverse sources enables you to prepare an inclusive dataset.

Lack of Accountability

If there is an instance of misuse of an AI system like deepfakes, it can be difficult to impart justice to the victims. This is because without a regulatory framework, no specific stakeholder can be held responsible.  Having a robust set of artificial intelligence regulations helps resolve this issue by clearly defining the roles of all stakeholders involved in AI deployment.

With such an arrangement, developers, users, deployers, and any other entity involved can be held accountable for any mishaps. To foster transparency, regulatory frameworks should also make it compulsory to document the training process of AI models and how they make any specific decision.

Important AI Regulatory Frameworks Around the World

Let’s discuss some artificial intelligence laws enforced by various countries around the world:

India

Currently, India lacks specific codified laws that regulate artificial intelligence. However, some frameworks and guidelines were developed in the past few years to introduce a few directives:

• Digital Data Protection Act, 2023, which is yet to be enforced to manage personal data. 
• Principles for Responsible AI, February 2021, contains provisions for ethical deployment of AI across different sectors.
• Operationalizing Principles for Responsible AI, August 2021, emphasized the need for regulatory policies and capacity building for using AI.
• National Strategy for Artificial Intelligence, June 2018, was framed to build robust AI regulations in the future.

A draft of the National Data Governance Framework Policy was also introduced in May 2022. It is intended to streamline data collection and management practices to provide a suitable ecosystem for AI-driven research and startups.

To further promote the use of AI, the Ministry of Electronics and Information Technology (MeitY) has created a committee that regularly develops reports on development and safety concerns related to AI.

EU

The European Union (EU), an organization of 27 European countries, has framed the EU AI Act to govern the use of AI in Europe. Adopted in March 2024, it is the world’s first comprehensive law on artificial intelligence regulations.

While framing the law, different applications of AI were analyzed and categorized according to the risks involved in them. The Act categorizes AI applications based on risk levels:

• Unacceptable Risk: This includes applications like cognitive behavioral manipulation and social scoring. Real-time remote biometric identification is permitted under stringent conditions.

• High Risk: This includes AI systems that negatively impact people’s safety or fundamental rights. Under this category, services using AI in the management of critical infrastructure, education, employment, and law enforcement have to register in the EU database. 

To further ensure safety, the law directs Generative AI applications such as ChatGPT to follow the transparency norms and EU copyright law. More advanced AI models, such as GPT-4, are monitored, and any serious incident is reported to the European Commission.

To address issues such as deepfake, this AI law has made provisions that AI-generated content involving images, audio, or video should be clearly labeled.

The intent of the EU AI Act is to promote safe, transparent, non-discriminatory, ethical, and environment-friendly use of AI. The Act also directs national authorities to provide a conducive environment for companies to test AI models before public deployment.

USA

Currently, there is no comprehensive law in the USA that monitors AI development, but several federal laws address AI-related concerns. In 2022, the US administration proposed a blueprint for an AI Bill of Rights. It was drafted by the White House Office of Science and Technology (OSTP) in collaboration with human rights groups and common people. The OSTP also took input from companies such as Microsoft and Google.

The AI Bill of Rights aims to address AI challenges by building safe systems and avoiding algorithmic discrimination. It has provisions for protecting data privacy and issuing notices explaining AI decisions for transparent usage. The bill also necessitates human interventions in AI operations.

Earlier, the US issued some AI guidelines, such as the Executive Order on the Safe, Secure, and Trustworthy Use of Artificial Intelligence. It requires AI developers to report potentially threatening outcomes to national security.

Apart from this, the Department of Defense, the US Agency for International Development, and the Equal Employment Opportunity Commission have also issued orders for the ethical use of AI. Industry-specific bodies like the Federal Trade Commission, the US Copyright Office, and the Food and Drug Administration have implemented regulations for ethical AI use. 

China

China has different AI regulatory laws at national, regional, and local levels. Its Deep Synthesis Provisions monitors deepfake content, emphasizing content labeling, data security, and personal information protection.

The Internet Information Service Algorithmic Recommendation Management Provisions mandates AI-based personalized recommendation providers to protect your rights. These provisions are grouped as general provisions, informed service norms, and user rights protection. It includes directions to protect the identity of minors and allows you to delete tags about your personal characteristics.

To regulate Generative AI applications, China recently came up with interim measures on generative AI. It directs GenAI service providers that they should not endanger China’s national security or promote ethnic discrimination.

To strengthen the responsible use of AI, China has also deployed the Personal Information Protection Law, the New Generation AI Ethics Specification, and the Shanghai Regulations.

Several other nations, including Canada, South Korea, Australia, and Japan, are also taking proactive measures to regulate AI for ethical use.

Challenges in Regulating AI

The regulation of AI brings with it several challenges owing to its rapid evolution and complex nature. Here are some of the notable challenges:

Defining AI

There are varied views regarding the definition of artificial intelligence. It is a broad term that involves the use of diverse technologies, including machine learning, robotics, and computer vision. As a result, it becomes difficult to establish a one-size-fits-all regulatory framework. For example, you cannot monitor AI systems like chatbots, automated vehicles, or AI-powered medical diagnostic tools with the same set of regulations.

Cross-Border Consensus

Different regions and nations, such as the EU, China, the US, and India, are adopting different regulations for AI. For example, the AI guidelines of the EU emphasize transparency, while those of the US focus on innovation. Such an approach creates operational bottlenecks in a globalized market, complicating compliance for multinational entities.

Balancing Innovation and Regulation

Excessive AI regulation can hamper the development of AI to the full extent, while under-regulation can lead to ethical breaches and security issues. Most companies avoid implementing too many regulations, fearing that it could reduce innovation.

Rapid Pace of Development

The speed with which AI is developing is outpacing the rate at which regulations are developed and enforced. For instance, considerable damage occurred even before regulatory bodies could create rules against deepfake technology. It is also challenging for regulators to create long-term guidelines that can adapt to the rapidly evolving nature of AI technologies.

Lack of Expertise among Policymakers

Effective AI regulation requires policymakers to have a good understanding of the potential risks and mitigation strategies of this technology.  Policymakers usually lack this expertise, leading to the designing of policies that are irrelevant or insufficient for proper monitoring of AI usage.

Key Components of Effective AI Regulation

Here are a few components that are essential to overcome hurdles in framing artificial intelligence regulations:

Data Protection

AI systems are highly data-dependent, which makes it crucial for you to prevent data misuse or mishandling. Regulations like  GDPR or HIPAA ensure that personal data is utilized with consent and responsibly.

You can take measures such as limiting data retention time, masking data wherever required, and empowering individuals to control how their personal information is used.

Transparency

AI systems often operate as black boxes that are difficult to understand. Having transparency ensures that the processes behind AI decision-making are accessible for verification.

To achieve this, the regulatory framework mandates companies to design AI products with auditing features so that the underlying decision-making logic is accessible for verification. If there are any discrepancies, you can challenge the AI decisions, and the developers will be held accountable for providing remedies.

Human Oversight

A fully autonomous AI system makes all decisions on its own and can sometimes take actions that lead to undesirable consequences. As a result, it is important to have some proportion of human intervention, especially in sectors such as healthcare, finance, and national security. 

For this, you can set up override mechanisms where humans can immediately intervene when AI behaves irrationally or unexpectedly.

Global Standards and Interoperability

With the increase in cross-border transactions, it is essential to develop AI systems that facilitate interoperability and adhere to global standards. This will simplify cross-border operations, promote international collaboration, and reduce legal disputes over AI technologies.

Way Forward

There has been an increase in instances of misuse of AI, including deepfakes, impersonations, and data breaches. Given this trend, artificial intelligence regulations have become the need of the hour.

Several countries have introduced legal frameworks at basic or advanced levels to address many artificial intelligence-related questions. However, we still need to fully understand the implications AI will have on human lives.

In the meantime, it is the responsibility of policymakers and technical experts to create public awareness about the impacts of good and bad use of AI. This can be done through education, training, and public engagement through digital platforms. With these initiatives, we can ensure that AI’s positive aspects overpower its negative consequences.

FAQs

To whom does the EU AI Act apply?

The EU AI Act applies to all businesses operating within the EU. It is compulsory for providers, deployers, distributors, importers, and producers of AI systems to abide by the rules of the EU AI Act. 

What are some other examples of data protection regulations?

Some popular examples of the data protection regulations include:

• Digital Personal Data Protection (DPDP) Act, India
• General Data Protection Regulation (GDPR), EU
• California Consumer Privacy Act (CCPA), US
• Protection of Personal Information Act (POPIA), South Africa
• Personal Information Protection and Electronic Documents Act (PIPEDA), Canada

Object-oriented programming (OOP) is the most widely used programming paradigm. It enables you to organize and manage code in a structured way. Like other general-purpose programming languages such as Java, C++, and C#, Python also supports OOP concepts, making it an OOP language. To learn more about Python OOPs and how to apply them effectively in your projects, you have come to the right place.

Let’s get started!

What Is OOPs in Python?

Python supports OOPs, which allows you to write reusable and maintainable Python programs using objects and classes. An object is a specific instance of a class that represents a real-world entity, such as a person, vehicle, or animal. Each object is bundled with attributes (characteristics) and methods (functions) to describe what it is and what it can do. A class is like a blueprint or template that defines the attributes and functions every object should have.

An OOP Example

Let’s understand this clearly by considering a scenario where you are designing a system to manage vehicles. Here, a class can be a template for different types of vehicles. Each class will describe common vehicle characteristics like color, brand, and model, along with functions such as starting or stopping. 

For instance, you might have a class called “Car,” which has these attributes and behaviors. Then, an object would be a specific car, such as a red Mercedes Benz. This object has all the features defined in the class but with particular details: “red” for color, “Mercedes Benz” for brand, and “Cabriolet” for the model. Another object could be a yellow Lamborghini, which has “yellow” for color, “Lamborghini” for the brand, and “Coupe” for the model. 

In this way, the class is a blueprint, while the object is a unique instance of that blueprint with real-world information. 

How Do You Implement Classes and Objects in Python?

To create a class in Python, you must use a keyword class as follows:

class classname:
   <statements> 

For example, 

class demo:
	name = "XYZ"

Once you define a class, you can use it to create objects using the following syntax:

object_name = classname()
print(object_name.field_name)

For instance,

Object1 = demo()
print(Object1.name)

This will produce XYZ as output.

Instance Attributes and Methods 

Each object (instance) of a class can have its own attributes. In the above example, Car is a class with attributes like color, model, and brand. Using an __init__ method, you can initialize these attributes whenever a new object is created. You can pass any number of attributes as parameters to the __init__method,  but the first one must always be named self. When you create a new instance of a class, Python automatically forwards that instance to the self parameter. This allows you to ensure that attributes like color, brand, and model are specific to an object rather than being shared among all instances. 

Objects can also have methods, which are functions that belong to a class and work with specific instances of that class. They use an object’s attributes to perform an action. The first parameter of an instance method is always self, which refers to the object on which the method is being called. Using self parameter, the object methods can access and modify the attributes in the current instance. Inside an instance method, you can use a self to call other methods of the same class for the specific instance. 

To get more idea on this, let’s create a simple implementation for the Car class using classes and objects:

# Define the Car class
class Car:
    def __init__(self, color, brand, model):
        self.color = color  # Attribute for color
        self.brand = brand  # Attribute for brand
        self.model = model  # Attribute for model
    
    # Start Method for Car
    def start(self):
        print(f"The {self.color} {self.brand} {self.model} is starting.")
    
    # Stop Method for Car
    def stop(self):
        self.start() # Calling another method
        print(f"The {self.color} {self.brand} {self.model} is stopping.")

# Creating two objects of the Car class
car1 = Car("red", "Mercedes Benz", "Cabriolet")
car2 = Car("yellow", "Lamborghini", "Coupe")

# Calling the methods of the Car class to execute Car1 object
car1.start()  
car1.stop()   

# Calling the methods of the Car class to execute Car2 object
car2.start()  
car2.stop()   

Click here to try the given program and customize it according to your needs. 

Here is a sample output: 

The above program demonstrates how OOP helps in modeling real-world entities and how they interact with each other.  

Key Principles of OOP

Apart from classes and objects, there are four more principles that make Python an object-oriented programming language. Let’s take a look at each of them:

Inheritance

Inheritance is a key concept in OOPs that provides the ability for one class to inherit the attributes and methods of another class. A class that derives these characteristics is referred to as the child class or derived class. On the other hand, the class from which data and functions are inherited is known as the parent class or base class. 

By implementing inheritance in Python programs, you can efficiently reuse the existing code in multiple classes without rewriting it. This is done by creating a base class with common properties and behaviors. Then, you can derive child classes that inherit the parent class functionality. In the derived classes, you have the flexibility to add new features or override existing methods by preserving the base class code. 

Types of Python Inheritance

Single Inheritance

In single inheritance, a child class helps you inherit from one base class. Let’s extend the above Car class to model a vehicle management system through single inheritance:

# Define the Vehicle class (Parent class)
class Vehicle:
    def __init__(self, color, brand, model):
        self.color = color  
        self.brand = brand
        self.model = model
    
    # Start Method for Vehicle
    def start(self):
        print(f"The {self.color} {self.brand} {self.model} is starting.")
    
    # Stop Method for Vehicle
    def stop(self):
        print(f"The {self.color} {self.brand} {self.model} is stopping.")

class Car(Vehicle): # Car is a child class that inherits from the Vehicle class
# Defining function for Car
    def carfunction(self):
	    print("Car is functioning")

# Creating an object of the Car class
car1 = Car("red", "Mercedes Benz", "Cabriolet")

# Calling the methods
car1.start()
car1.carfunction()  
car1.stop()   

Sample Output:

Hierarchical Inheritance

In hierarchical inheritance, multiple derived classes inherit from a single base class, which helps different child classes to share functionalities. Here is the modified vehicle management program to illustrate hierarchical inheritance: 

class Bike(Vehicle):  # Bike inherits from Vehicle
    def kick_start(self):
        print("Bike is kick-started.")

class Jeep(Vehicle):  # SportsBike inherits from Bike
    def off_road(self):
        print("Jeep is in off-road mode!")

# Creating an object of Bike and Jeep child class
bike1 = Bike("yellow", "Kawasaki", "Ninja")
jeep1 = Jeep("Black", "Mahindra", "Thar")
bike1.kick_start() 
bike1.start()  
bike1.stop()
jeep1.off_road() 
jeep1.start()
jeep1.stop()

Sample Output:

Multilevel Inheritance

Multilevel inheritance is referred to as a chain of inheritance, which enables a child class to inherit from another child class. Here is the code fragment demonstrating multilevel inheritance that you can add to the above vehicle management program:

class SportsBike(Bike):  # SportsBike inherits from Bike
   
    def drift(self):
        print(f"The {self.color} {self.brand} {self.model} is drifting!")

# Creating an object of SportsBike
sports_bike = SportsBike("yellow", "Kawasaki", "Ninja")
sports_bike.start()  
sports_bike.kick_start()  
sports_bike.drift()  
sports_bike.stop()

Sample Output:

Multiple Inheritance

In multiple inheritance, a derived class can inherit from more than one base class. This helps the child class to combine functions of multiple parent classes. Let’s include one more parent class in the vehicle management program to understand the multiple inheritance concept:

# Define the Vehicle class
class Vehicle:
    def __init__(self, color, model):
        self.color = color  # Attribute for color
        self.model = model  # Attribute for model

    def start(self):
        print(f"The {self.color} {self.model} is starting.")
    
    def stop(self):
        print(f"The {self.color} {self.model} is stopping.")

# Define the Manufacturer class
class Manufacturer:
    def __init__(self, brand):
        self.brand = brand  # Attribute for brand

    def get_brand(self):
        print(f"This vehicle is manufactured by {self.brand}.")

# Define the Car class that inherits from both the Vehicle and the Manufacturer
class Car(Vehicle, Manufacturer):
    def __init__(self, color, model, brand):
        Vehicle.__init__(self, color, model)
        Manufacturer.__init__(self, brand)

    def show_details(self):
        self.get_brand()
        print(f"The car is a {self.color} {self.brand} {self.model}.")

# Creating an object of Car
car = Car("red", "Cabriolet", "Mercedes Benz")
car.start()
car.show_details()
car.stop()

Sample Output:

Polymorphism

Polymorphism refers to the capability of different objects to respond in multiple ways using the same method or function call. Here are the four ways to achieve polymorphism in Python:

Duck Typing

In duck typing, Python allows you to use an object based on its attributes and method instead of its type. This indicates that it only considers if the object has a required method and provides support for dynamic typing in Python. 

For example, if an object looks like a list, Python will consider it a list type. With duck typing, you can focus on what an object can do instead of worrying about its specific type. 

Let’s look at an example of how duck typing is implemented in Python:

# Define a class Dog with a method speak
class Dog:
    def speak(self):
        return "Yes, it barks bow bow"

# Define a class Cat with a method speak
class Cat:
    def speak(self):
        return "Yes, it cries meow meow"  

# Function that takes any animal object and calls its speak method
def animal_sound(animal):
    return animal.speak()  # Calls the speak method of the passed object

# Create instances of Dog and Cat
dog = Dog()
cat = Cat()

# Call animal_sound function with the dog and cat objects, printing their sounds
print(animal_sound(dog))  
print(animal_sound(cat))

Sample Output:

In the above code, the animal_sound() function works with any object passed to it as long as that object has a speak() method. The animal_sound() function does not check if the object is an instance of Dog, Cat, or another class; it just calls speak() on the object, assuming it will behave as expected. This flexibility through the duck typing concept enables the Python compiler to focus on what an object can do rather than its actual type or class.  

Method Overriding

Method overriding occurs when a subclass provides a specific implementation of a method that is already defined in its parent class. 

Here is an example:

# Base class Vehicle with a start method
class Vehicle:
    def start(self):
        return "Vehicle is starting."  

# Subclass Car that inherits from Vehicle and overrides the start method
class Car(Vehicle):
    def start(self):
        return "Car is starting."  

# Creating instances of Vehicle and Car
vehicle = Vehicle()
car = Car()

print(vehicle.start())  
print(car.start())

Sample Output:

Method Overloading

Python does not support traditional method overloading as Java does. However, you can implement it using default arguments or handling different input types. Let’s see an example:

class Calculator:
    def add(self, a, b=None):
        if b is not None:
            return a + b  
        return a  

# Create an instance of the Calculator class
calc = Calculator()

# Calling the add method with two arguments
print(calc.add(5, 10))

# Calling the add method with one argument
print(calc.add(5))      

Sample Output:

Operator Overloading

Operator overloading allows you to define custom methods for standard operators like + or -.

Here is an example:

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def __add__(self, other):
        return Point(self.x + other.x, self.y + other.y)

    def __repr__(self):
        return f"Point({self.x}, {self.y})"

p1 = Point(2, 3)
p2 = Point(4, 1)

p3 = p1 + p2
print(p3)  

Sample Output:

Encapsulation

Encapsulation is the practice of restricting direct access to certain attributes and methods of an object to protect data integrity. In Python, you can achieve data encapsulation by prefixing an attribute with a single underscore (_) or a double underscore (__). 

Attributes marked with a single underscore are considered protected. These attributes can be accessed from within the classes and their derived classes but not from outside the class. If the attributes prefixed with a double underscore are private, they are intended to be inaccessible from within or outside the class. This mechanism ensures better data security and helps you maintain the internal state of an object.

Let’s see an example to achieve encapsulation in Python:

class Person:
    def __init__(self, name, age, phone_number):
        self.name = name                # Public attribute
        self.age = age                  # Public attribute
        self._email = None              # Protected attribute
        self.__phone_number = phone_number  # Private attribute

    def get_phone_number(self):
        return self.__phone_number  # Public method to access the private attribute

    def set_phone_number(self, phone_number):
        self.__phone_number = phone_number  # Public method to modify the private attribute

    def set_email(self, email):
        self._email = email  # Public method to modify the protected attribute

    def get_email(self):
        return self._email  # Public method to access the protected attribute

# Creating an instance of the Person class
person = Person("Xyz", 20, "9863748743")

# Accessing public attributes
print(person.name)  
print(person.age)   

# Accessing protected attribute
person.set_email("xyz@sample.com")
print(person.get_email())  

# Accessing a private attribute using public methods
print(person.get_phone_number())  

# Modifying the private attribute using a public method
person.set_phone_number("123456789")
print(person.get_phone_number())

Sample Output:

Data Abstraction

Abstraction helps you hide complex implementation details and only show an object’s essential features. The Abstract Base Classes (ABC) module allows you to implement data abstraction in your Python program through abstract classes and methods. 

Here is an example of implementing abstraction:

# Importing ABC module to define abstract classes
from abc import ABC, abstractmethod

# Defining an abstract class Animal that inherits from ABC
class Animal(ABC):
