python-Theano

A scientific python library

Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays. Theano features: * tight integration with numpy - Use numpy.ndarray in Theano-compiled functions. * transparent use of a GPU * symbolic differentiation - Let Theano do your derivatives. * speed and stability optimizations – Get the right answer for log(1+x) even when x is really tiny. * dynamic C code generation - Evaluate expressions faster. * extensive unit-testing and self-verification – Detect and diagnose many types of mistake.
