1. Environment setup

Our project is developed upon MMAction2 v0.24.1, please follow their instruction to setup the environemtn.

2. Dataset preparation

Follow these instructions to setup the datasets

We provide pre-extracted scene feature and labels, and scene-distance-splitted subsets for the three datasets here (coming soon). Please place them in the data folder.

3. Training

Upon the original MMAction2 train and evaluation scripts, we wrote a simple script that combines the training and evalution tools/run.py.

For training and evaluating the whole SOAR model (require the pre-extracted scene label):

python tools/run.py configs/recognition/i3d/i3d_r50_dense_32x2x1_50e_ucf101_rgb_weighted_ae_edl_dis.py --gpus 0,1,2,3

For the unsupervised version that does not require the scene label:

python tools/run.py configs/recognition/i3d/i3d_r50_dense_32x2x1_50e_ucf101_rgb_ae_edl.py --gpus 0,1,2,3

4. Evaluation

Coming soon
