Pylearn2 basics

30 Mar 2015


Pylearn2 is a machine learning library. Most of its functionality is built on top of Theano. This means you can write Pylearn2 plugins (new models, algorithms, etc) using mathematical expressions, and Theano will optimize and stabilize those expressions for you, and compile them to a backend of your choice (CPU or GPU).

Official git repository is at

git clone

and my clone with things not (yet) merged into main repo can be cloned with:

git clone

The library is research-oriented, so you mind find it dificult to get it to work with your own dataset or to get it to work at all.

As of this writing the development mailing list if very low trafic while the user mailing list is active.
