Introduction

This is the official implementation of "Prototypical Contrast and Reverse Prediction: Unsupervised Skeleton based Action Recognition".

Requirements

• Python 3.6
• Pytorch 1.0.1

Datasets

• N-UCLA:
  Download transformed data from https://github.com/shlizee/Predict-Cluster/tree/master/ucla_github_pytorch/UCLAdata
• NTU RGB+D 60:
  Download transformed data from https://github.com/shlizee/Predict-Cluster.
• NTU RGB+D 120:
  Download raw data from https://github.com/shahroudy/NTURGB-D.
  Use ntu_gendata_for_predictCluster_right.py to reprocess raw data for view invariant transformation.

Put the data into the folder that matches the codes in pc_test.py

Usage

• pretrain and then linear evaluation:
  python pc_test.py
