Multi-Granularity Anchor-Contrastive Representation Learning for Semi-supervised Skeleton-based Action Recognition

Requirements

• python == 3.8.3
• pytorch == 1.11.0
• CUDA == 11.2

Data Preparation

Download the raw data of NTU-RGB+D, NW-UCLA, and Skeleton-Kinetics. Then the commands for data preprocessing are as follows,

python ./data_gen/ntu_gendata.py
python ./data_gen/ucla_gendata.py
python ./data_gen/kinetics_gendata.py

Training

• On NTU RGB+D cross-subject benchmark.

python main.py --config ./config/nturgbd-cross-subject/train_joint_aagcn.yaml

• On NTU RGB+D cross-view benchmark.

python main.py --config ./config/nturgbd-cross-view/train_joint_aagcn.yaml

• On NW-UCLA.

python main.py --config ./config/ucla/train_joint_aagcn.yaml

• On Skeleton-Kinetics.

python main.py --config ./config/kinetics-skeleton/train_joint_aagcn.yaml

Trained model
