scikits.learn: machine learning in Python

Easy-to-use and general-purpose machine learning in Python

scikits.learn is a Python module integrating classic machine learning algorithms in the tightly-knit world of scientific Python packages (numpy, scipy, matplotlib).

It aims to provide simple and efficient solutions to learning problems that are accessible to everybody and reusable in various contexts: machine-learning as a versatile tool for science and engineering.

Features:

• Solid: Supervised learning: Support Vector Machines, Generalized Linear Models.
• Work in progress: Unsupervised learning: Clustering, Gaussian mixture models, manifold learning, ICA, Gaussian Processes
• Planed: Gaussian graphical models, matrix factorization

License:

Open source, commercially usable: BSD license (3 clause)
