A Torch implementation of the Neural Turing Machine model described in this paper by Alex Graves, Greg Wayne and Ivo Danihelka.

This implementation uses an LSTM controller with one read head and one write head.

Torch7 (of course), as well as the following libraries:

penlight

nn

optim

nngraph

All the above dependencies can be installed using luarocks. For example:

luarocks install nngraph

For the copy task:

th tasks/copy.lua

For the associative recall task:

th tasks/recall.lua
