This repository contains the code accompanying the paper Learning to Reason with Third-Order Tensor Products published at NeurIPS, 2018. It encompasses our implementation of the Tensor Product Representation Recurrent Neural Network (TPR-RNN) applied to the bAbI tasks with SOTA results. A download script for a pretrained model is provided.

Requirements

• Python 3
• Tensorflow==1.11.0
• Seaborn==0.9.0
• Sklearn==0.0

Make sure to upgrade pip before installing the requirements.

pip3 install -r requirements.txt
sh download_data_and_model.sh

Usage

Run the pre-trained model.

python3 evaluation.py

Train from scratch. (Look at the train.py files for details)

python3 train.py

Generate small hierarchically clustered similarity matrices of a random set of sentences using different internal representations and the cosine similarity.

python3 cluster_analysis.py

Results

With this code we achieved the following error (rounded to two decimal places) when trained on all bAbI tasks simultaneously. In the appendix of the paper we provide a breakdown per task.

task	run-0	run-1	run-2	run-3	run-4	run-5	run-6	run-7	best	mean	std
all	1.50	1.69	1.13	1.04	0.78	0.96	1.20	2.40	0.78	1.34	0.52
