Spatial-Temporal Asynchronous Normalization for Unsupervised 3D Action Representation Learning

Human Activity Discovery With Automatic Multi-Objective Particle Swarm Optimization Clustering With Gaussian Mutation and Game Theory

“…after achieving the features, they applied the KNN classifier to group the activities. In [23], in addition to using auto-encoder, they normalized motion sequence based on spatial-temporal asynchronous method during the process of auto-encoder. They pruned the temporal information that had less effect on the learning process.…”
