Neural Arithmetic Logic Units

[WIP]

This is a PyTorch implementation of Neural Arithmetic Logic Units by Andrew Trask, Felix Hill, Scott Reed, Jack Rae, Chris Dyer and Phil Blunsom.

API

Experiments

To reproduce "Numerical Extrapolation Failures in Neural Networks" (Section 1.1), run:

python failures.py

This should generate the following plot:

To reproduce "Simple Function Learning Tasks" (Section 4.1), run:

python function_learning.py

This should generate a text file called interpolation.txt with the following results. (Currently only supports interpolation, I'm working on the rest. Also getting nans which I'm investigating.)
