Action Transformer: A Self-Attention Model for Short-Time Pose-Based Human Action Recognition
Overview
Paper Summary
The Action Transformer (AcT), a purely self-attentional model, excels at recognizing short-time human actions from 2D pose data. Outperforming previous methods on a new dataset, MPOSE2021, AcT also shows promise for low-latency, real-time applications due to its efficient design.
Explain Like I'm Five
Scientists found a new computer brain that's really good at figuring out what people are doing, like jumping or waving, just by looking at their outline. It can do this super fast, almost instantly!
