Learning Representations that Support Extrapolation

Code for the paper Learning Representations that Support Extrapolation.

Visual Analogy Extrapolation Challenge (VAEC)

The directory ./VAEC_dataset_and_models contains code for generating the VAEC dataset, and code for all models used for this dataset. To generate the VAEC dataset, navigate to ./VAEC_dataset_and_models/dset_gen/ and run the following command to generate the Translation Extrapolation Regime:

python3 ./VAEC_trans_extrap.py

and the following command to generate the Scale Extrapolation Regime:

python3 ./VAEC_scale_extrap.py

Or the dataset can be downloaded from DataSpace.

To train and evaluate any of the models described in the paper, run the corresponding the script in the ./VAEC_dataset_and_models/scripts/ directory. For instance, to train and evaluate networks with context normalization on the Translation Extrapolation Regime, navigate to ./VAEC_dataset_and_models/, and run the following command:

./scripts/context_norm_trans_extrap.sh

Similarly, to train and evaluate networks with context normalization on the Scale Extrapolation Regime, run the following command:

./scripts/context_norm_scale_extrap.sh

Dynamic Object Prediction

The directory ./dynamic_object_prediction contains code to generate the dynamic object prediction task, and code for all models used on this task. To train and evaluate all models described in the paper, navigate to ./dynamic_object_prediction and run the following command:

python3 ./main_script.py

Visual Analogy Task from Learning to Make Analogies by Contrasting Abstract Relational Structure

The directory ./LABC_visual_analogy_task contains code for all models used on the dataset from Learning to Make Analogies by Contrasting Abstract Relational Structure.

The dataset can be downloaded from https://github.com/deepmind/abstract-reasoning-matrices. Download the extrapolation dataset (inside the ./analogies directory). Create a directory inside ./LABC_visual_analogy_task/datasets/ called extrapolation, and place the files for the dataset in this directory.

To train and evaluate any of the models described in the paper, run the corresponding script. For instance, to train networks using source/target context normalization, navigate to ./LABC_visual_analogy_task/ and run the following command:

./source_targ_norm_train.sh

To evaluate these networks, run the following sommand:

./source_targ_norm_eval.sh

Prerequisites

To generate VAEC dataset:

For simulations using VAEC dataset:

For simulations using Dynamic Object Prediction Task or Visual Analogy Task from Learning to Make Analogies by Contrasting Abstract Relational Structure:

Authorship

Code for generating the VAEC dataset, and simulations using the VAEC dataset and Visual Analogy Task from Learning to Make Analogies by Contrasting Abstract Relational Structure was written by Taylor Webb.

Code for the Dynamic Object Prediction Task was written by Zachary Dulberg.

Some of the code for simulations using the VAEC dataset was originally modified from code in this repository.
