Top 16 Open Source Deep Learning Libraries and Platforms


We bring to you the top 16 open source deep learning libraries and platforms. TensorFlow is out in front as the undisputed number one, with Keras and Caffe completing the top three.



Deep Learning is an continuously-growing, popular part of a broader family of machine learning methods, based on data representations. As a relatively new concept, the vast amount of resources can be a touch overwhelming for those either looking to get into the field, or those already engraved in it. A good way of staying updated with the latest trends is to interact with the community by engaging and interacting with the deep learning open source projects that are currently available.

Top 16 deep learning libraries

Fig. 1: Top 16 open source deep learning libraries by Github stars and contributors, using log scale for both axes. The color of the circle shows the age in days (greener - younger, bluer - older), computed from Start date given on github under Insights / Contributors.

By all measures, TensorFlow is the undisputed leader. Keras, Caffe, Microsoft Cognitive Toolkit, and PyTorch completing the top five.

Below you will find the full list, ordered by stars, with a brief outline and further links. We hope you will enjoy collaborating and learning more by using the links provided for each library:

 

  1. TensorFlow was originally developed by researchers and engineers working on the Google Brain Team within Google’s Machine Intelligence research organization. The system is designed to facilitate research in machine learning, and to make it quick and easy to transition from research prototype to production system.
    Stars: 96655, Contributors: 1432, Commits: 31714, Start: 1-Nov-15. Github URL: TensorFlow.
  2. Keras is a high-level neural networks API, written in Python and capable of running on top of TensorFlow, CNTK, or Theano.
    Stars: 28385, Contributors: 653, Commits: 4468, Start: 22-Mar-15. Github URL: Keras.
  3. Caffe is a deep learning framework made with expression, speed, and modularity in mind. It is developed by the Berkeley Vision and Learning Center (BVLC) and community contributors.
    Stars: 23750, Contributors: 267, Commits: 4128, Start: 8-Sep-15. Github URL: Caffe.
  4. Microsoft Cognitive Toolkit (Previously CNTK) is a unified deep learning toolkit that describes neural networks as a series of computational steps via a directed graph.
