Theano: Lower Memory Usage

by Roy Xue for Python Software Foundation

Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. I'd like to analyse and optimize the memory used by Theano functions during their execution. Current code only does dumb greedy approach to memory allocation coupled with a garbage collector to deallocate memory once unneeded. This project would to do better by possibly lowering the maximum memory allocated at once and avoiding reallocations.
