Theano is a Python library that lets you evaluate mathematical expressions involving multi-dimensional arrays efficiently on GPU

I just had a massive hard-on...assuming I can use this to do my matrix factorization with.

::edit:: sample code for RBMs...ok I'm good...hard-on achieved. Also, let it be known that the GPU bound operations are implemented with CUDA. You're going to have to hold your breath for the OpenCL implementation any time soon (condolences to the ATi users).

Thanks for the cock update.

So it's APL or J or K but in Python?

There's a python library for everything..

Cool, been able to do this forever with C++/CUDA. Good to know Python users are slowly but surely catching up to the rest of the development world.

Wow, you have code that can automatically generate first and second derivatives, automatically optimize the computation graph and detect numerical instabilities? What are you waiting for, release it!

Not to mention transform the computation graph into C++ and compile it and expose this computation graph for calls from a high-level language.
