Grouped Spatial-Temporal Aggretation for Efficient Action Recognition

Pytorch implementation of paper Grouped Spatial-Temporal Aggretation for Efficient Action Recognition. arxiv

Prerequisites

PyTorch 1.0 or higher
python 3.5 or higher

Data preparation

Please refer to TRN-pytorch for data preparation on Something-Something.

Training

For GST-Large: python3 main.py --root_path /path/to/video/folder --dataset somethingv1 --checkpoint_dir /path/for/saving/checkpoints/ --type GST --arch resnet50 --num_segments 8 --beta 1
For GST: python3 main.py --root_path /path/to/video/folder --dataset somethingv1 --checkpoint_dir /path/for/saving/checkpoints/ --type GST --arch resnet50 --num_segments 8 --beta 2 --alpha 4
For more details, please type python3 main.py -h

Pretrained Models

	Something-v1	Something-v2
GST(alpha=4, 8 frames)	47.0	61.6
GST(alpha=4,16 frames)	48.6	62.6
GST-Large(alpha=4,8 frames)	47.7	62.0

results are reported based on center crop and 1 clip sampling.
