Recurrent Entity Networks

This repository contains an independent TensorFlow implementation of recurrent entity networks from Tracking the World State with Recurrent Entity Networks. This paper introduces the first method to solve all of the bAbI tasks using 10k training examples.

Setup

1. Download the datasets by running download_datasets.sh or from The bAbI Project.
2. Run prep_datasets.py which will convert the datasets into TFRecords.
3. Run python -m entity_networks.main to begin training on QA1.
4. Run ./run_all.sh to train on all tasks.

Dependencies

• TensorFlow v0.11
