Data Preparation

1. Download the features of THUMOS14 from dataset.zip.
2. Place the features inside the ./data folder.

Train and Evaluate

1. Train the CASE model by run

   python main_case.py --exp_name CASE

2. The pre-trained model will be saved in the ./outputs folder. You can evaluate the model by running the command below.

   python main_case.py --exp_name CASE --inference_only

   We provide our pre-trained checkpoints in checkpoints.zip
