Getting started

Our method proposes a two-stage training method for the task of long-term action anticipation.

• pretraining directory contains code for stage 1. This stage involves training a model for the task of snippet-based action anticipation.

• src directory contains code for stage 2. This stage uses the frozen networks from stage 1 and trains two other networks for the task of long-term action anticipation.

• The file env.yml provides dependencies for the training environment

• To train the model, download the features to the path given in the .py file or change the path to a custom location.

For our training setup, we use these directories.

• pretraining_data provides the data specific to our training for stage 1.

• For our implementation, we save data in a directory data within this top-level directory. For training the data needs to be downloaded from cited sources.

  • The features and annotations for Epic-Kitchens-55 and EGTEA can be downloaded from https://github.com/facebookresearch/ego-topo
  • The features and annotations for Breakfast can be downloaded from https://github.com/yabufarha/ms-tcn

• We also add sample run scripts for the codes in the directory run_scripts
