Top Deep Learning Frameworks

Deep learning, a vital element of data science, is a class of machine learning that works similarly to the human brain. Simply, it can be considered a proxy for predictive modeling, a statistical technique to predict future states. Many of the top deep learning frameworks make this process quicker and more straightforward, making it advantageous to data scientists who gather, analyze, and interpret massive amounts of data. 

Deep learning frameworks differ from traditional ML frameworks in linearity. While traditional ones are linear, deep learning frameworks have stacked algorithms in complex hierarchies (or layers). Each algorithm in the hierarchy performs a nonlinear transformation on its input and outputs a statistical model using what it has learned. Iterations keep pushing until the output is accurate enough. Thus, the word “deep” justifies the presence of multiple processing layers that the data must go through. 

Convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory (LSTM), and deep belief networks (DBN) are some popular deep learning frameworks that are commonly used for many commercial applications and use cases like NLP, computer vision, etc. This article enlists some of the top deep learning frameworks.

Top deep learning frameworks

  1. Sonnet

Sonnet is an advanced framework for deep learning developed by Google’s DeepMind for TensorFlow, its a fundamental framework due to its versatility and adaptability for creating even higher-level frameworks. Sonnet does not replace TensorFlow for DL-based tasks but makes it easier for the users to construct neural networks. Before it, developers had to be proficient with all underlying TensorFlow graphs, but now all they have to do is construct Python objects and connect them separately to form a TensorFlow computation graph. 

It features multiple pre-defined modules snt.Linear, snt.Conv2D, snt.BatchNorm, etc. Users can also write customized modules and submodules to create models. These models can be readily integrated using raw TF codes or codes written in other advanced languages.

Kaldi is an open-source deep learning toolkit explicitly designed for speech recognition based on C++. The framework is highly flexible and efficient in training acoustic models (statistical representations of acoustic information). Kaldi compiles the OpenFst toolkit to modernize coding and provide several “recipes” for model training. 

The framework has bindings for Python, MATLAB, Java, and other programming languages. Many companies like Microsoft, Google, IBM, Apple, and others use Kaldi under the Apache 2.0 license.

  1. Theano

Theano is a Python-based library built on NumPy that enables you to define, optimize, and evaluate mathematical expressions in deep learning with multi-dimensional arrays. Named after “Theano,” a greek mathematician, the library was introduced by the Montreal Institute for Learning Algorithms in 2007. It features a transparent use of GPU for data-intensive computations, avoids nasty bugs in complex computations, supports dynamic C code generation, and tools for detecting potential problems. 

Theano functions in three stages: first, it defines the objects or variables; next, it progresses through phases to determine the mathematical expressions; and finally, it evaluates expressions by receiving input values.

Companies like Vizual.ai, Vuclip, Zetaops, and others actively use Theano in their technology stacks. 

  1. Scikit-learn 

Next on our list of top deep learning frameworks is Scikit-learn, a Python-based toolkit, that was unveiled in 2007 during the Google Summer of Code project hosted by David Cournapeau. It was designed to operate and facilitate machine learning and artificial intelligence algorithms and work in conjunction with several frameworks like NumPy, SciPy, Matplotlib, Pandas, etc.

Other than supporting deep learning, it is used for statistical modeling with regression, classification (K-nearest neighbors), clustering (K-means and K-means++), preprocessing, and dimensionality reduction. 

The toolkit is being actively used by organizations like Spotify, Inria, and J.P. Morgan to enhance their linear algebra and statistical analysis.
