Learning the Predictability of the Future

Code from the paper Learning the Predictability of the Future.

Website of the project in hyperfuture.cs.columbia.edu.

This code is built on the DPC code in github.com/TengdaHan/DPC. We also used hyperbolic networks from github.com/geoopt/geoopt and hyperbolic operations from the geoopt library.

Under scripts there are example bash files to run the self-supervised training and finetuning, and the supervised training and testing of our model.

You will have to modify the paths to the datasets and to the dataset info folder (read more in the datasets section).

Run python main.py --help for information on arguments.

Be sure to have the external libraries in requirements.txt installed.

If you use this code, please consider citing the paper as:

Datasets

We train our framework on four different datasets: Kinetics600, FineGym, MovieNet, and Hollywood2. The data can be downloaded from the original sources.

Other dataset information necessary to run our models (like train/test splits and class hierarchies) can be found in this link (dataset_info.tar.gz). This information is in general the same as in the original datasets, but we provide it to avoid any inconsistencies. You will have to set the path to that folder in --path_data_info.

As a reminder, you can extract the content from a .tar.gz file by using tar -xzvf archive.tar.gz.

Pretrained models

The pretrained models reported in our paper can be found in this link (checkpoints.tar.gz):

Each folder (one for each model) contains a .pth file with the checkpoint.

To resume training or to pretrain from one of these pretrained models, add the path to that checkpoint to the
--resume or --pretrain arguments.

In case there is any doubt or problem, feel free to send us an email.
