Theano is a python library that allows you to define, optimize, and evaluate mathematical expressions involving multidimensional arrays efficiently. The state of a layer of neurons is the set of all the weights of its connections that describe it at that point in time. This ways you skip the embedding layer and use your own precomputed word vectors instead. The forward pass is well explained elsewhere and is straightforward to understand, but i derived the backprop equations myself and the backprop code came without any explanation whatsoever.

The networks used here have short term memory in that each prediction is based on joining states from the last two or three moves. Please read the blog post that goes with this code.
