EPIC-KITCHENS-100 UDA Challenge Source Code

This repository contains the code used to produce the baseline results (TA3N) for the EPIC-KITCHENS-100 UDA Challenge.

Some modifications have been made to the original TA3N code base to produce results on EPIC-KITCHENS-100 including:

1. Multiple classification heads to produce predictions for verb and nouns.
2. Modified dataloader to load EPIC-KITCHENS-100 pre-extracted features.
3. Modified training scripts to run the EPIC-KITCHENS-100 UDA baselines based. These have been modified fromscript_train_val.sh in the original repository.

The original TA3N code and ICCV publication can be found in the provided hyperlinks.

Usage

We provide modified training scripts for TA3N to replicate EPIC-100 UDA Challenge results.

1. Install dependecies

   • conda env create -f environment.yml

2. Download annotations and features.

   • Annotations should be downloaded to the folder ./annotations and extracted features to ./data.
     • Features: https://www.dropbox.com/sh/hsf8assfb9pzjos/AABqlWHx3YQATJZ_Gqnnhsj1a?dl=0
     • Annotations: https://github.com/epic-kitchens/epic-kitchens-100-annotations/tree/master/UDA_annotations
   • Alteratively variables in the bash scripts (path_labels_root="annotations", path_data_root="data) can be modified to match the location of the labels/features on your machine.

3. Replicate results with the provided bash scripts:

   • ./script_test_ta3n.sh to re-produce TA3N domain adaptation results
   • ./script_test_source_only.sh to re-produce source-only results

4. Each script will generate a submission scripttest.json which can be uploaded to the UDA Codalab challenge to replicate the results. To re-train models, set train=true in the bash scripts.
