This repository provides code to train, validate and test our models on the EPIC-KITCHENS-55 an EPIC-KITCHENS-100 datasets for the tasks of action anticipation and action recognition.
Follow the RU-LSTM repository to download the RGB, Flow, Obj features and the train/val/test splits and keep them in the data/ek55 or data/ek100 folder depending on the dataset.
For ROI features we consider the union of the hand-object interaction bbox annotations provided by the authors of EPIC-KICTHENS-100 (link) as input and extract RGB features with TSN as explained here.
Pretrained models are available only for the EPIC-KITCHENS-100 dataset trained on it's train split. They are provided in the folders models_anticipation and model_recognition.
To validate our model, run the following:
