Overview of machine learning tools in Python

• Scikit learn
• PyBrain - Reinforcement Learning, Artificial Intelligence and Neural Network Library.
• MLPy
• PyML
• LibSVM
• cuDNN - Cuda Deep Neural Network implementation by NVidia
  • Caffe - further extension to cuDNN

Python tools:

• NLTK - Natural Language Toolkit
• Oython libraries - a set of precompiled libraries for Windows

• LibSVM - a very good library of different SVM implementations by Chih-Chung Chang and Chih-Jen Lin. All the tools are avaliable here
• SVM Light - a large set of algorithms of SVM'a by Thorsten Joachims. It includs more complex versions of SVM:
  • SVM struct - Different of SVMs able to learn structured output
• List of software

• Ghost Miner - (licenced) very good and fast tools developed by KIS UMK in Toruń (Poland), distributed by Fujitsu (company FQS)
• Intemi - new projest (also KIS UMK in Toruń) currently under development
• Spider - my favourite Matlab toolbox (for free), it itegrate many other matlab, C and Java packages like LibSVM, Weka etc. I'm also developing this project and all my AddIns can be downloaded from here (in case of any problems please contact me on email).
• R-project in an open-source statistical programming language
• MLOSS project - repository of machine learning open source software
• Elefant - Machine learning project written in Python
• GPML - Gaussian Processes for Machine Learning Matlab & Octave Toolbox
• Oger - a Python toolbox for rapidly building, training and evaluating modular learning architectures on large datasets.

• SNAP - Graph analysis software developed on Stanford - C++ libraries + Python interface (SNAPY)

I did a simple comparison between Weka, RapidMiner and Knime - I did a model with 100 fold CV on dataset with a few thousands samples with 5NN classifier. Obtained results proofed that weka is the fastest tool (few seconds) Rapid Miner required few minutes, and Knime was the slowest (a few minutes). I've also compared it with Matlab Spider - I won't comment that results :).
