Top 20 Python Machine Learning Open Source Projects, updated
Open Source is the heart of innovation and rapid evolution of technologies, these days. This article presents you Top 20 Python Machine Learning Open Source Projects of 2016 along with very interesting insights and trends found during the analysis.
Continuing analysis from last year: Top 20 Python Machine Learning Open Source Projects, this year KDnuggets bring you latest top 20 Python Machine Learning Open Source Projects on Github. Strangely, some of the most active projects of last year have become stagnant and also some lost their position from top 20 (considering contributions and commits), whereas new 13 projects have entered into top 20.

We can see in the following chart that PyMVPA has highest contribution rate compare to all top projects in the list. Surprisingly, Scikit-learn has low contribution rate, despite maximum no. of contributors compare to other projects. Reason behind this could be that, as PyMVPA is a new project and going through early phases of development, leading to many commits because of new ideas/features development, defect fixing, refactoring etc. Whereas, Scikit-learn is old and stable project leading to less no. of improvements or defect fixing.
When we compare 2016 and 2015 projects which are part of both Top 20 list, we can see Pattern, PyBrain and Pylearn2 have no major contribution as well as no new contributors. Also, one prominent correlation can be seen in no. of contributors and no. of commits. Increase in contributors may cause increase in commits and I think that’s the magic of open source projects and community; it leads to brainstorming, new ideas and better software tools.
This was the analysis of Top 20 Python Machine Learning Open Source Projects 2016, based on no. of. contributors and no. of commits, by KDnuggets Team – Prasad and Gregory.
