Rank-aware Attention Network

Rank-aware Attention Network from 'The Pros and Cons: Rank-aware Temporal Attention for Skill Determination in Long Videos'.

BEST Dataset

Videos

The Bristol Everyday Skill Tasks (BEST) Dataset can be downloaded using python utils/download_videos.py data/BEST/BEST.csv <download_dir> --trim

The --trim flag extracts the part of the original video used in training/testing i.e. removing title sequences or unrelated tasks preceeding the start of the relevant task.

Features

The extracted i3d features for the BEST tasks and the EPIC-Skills tasks can be downloaded using bash utils/download_features.sh

Training/Test Splits

The split of training and test videos can be found under data/BEST/splits/<task_name>/<train|test>_vid_list.txt. The files containing the annotated pairs used for training and testing can be found at data/BEST/splits/<task_name>/<train|test>.txt.

We also include the EPIC-Skills training and testing pair files in the same format under data/EPIC-Skills/splits/<task_name>/<train|test>_split<split_num>.txt

Code

For tasks from EPIC-Skills run using:

python train.py data/EPIC-Skills/splits/<task>/train_split<split>.txt data/EPIC-Skills/splits/<task>/test_split<split>.txt <path_to_features> -e --transform --attention --diversity_loss --disparity_loss --rank_aware_loss

For tasks from BEST run using:

python train.py data/BEST/splits/<task>/train.txt data/BEST/splits/<task>/test.txt <path_to_features> -e --transform --attention --diversity_loss --disparity_loss --rank_aware_loss
