SAP: Self-Adaptive Proposal Model for Temporal Action Detection based on Reinforcement Learning

By Jingjia Huang, Nannan Li, Tao Zhang and Ge Li

The paper can be found here.

Introduction

Self-Adaptive Proposal (SAP) is a DQN based model for temporal action localization in untrimmed long videos. The temporal action detection process for SAP is naturally one of observation and refinement: observe the current window and refine the span of attended window to cover true action regions. SAP can learn to find actions through continuously adjusting the temporal bounds in a self-adaptive way. Experiment results on THUMOS’14 validate the effectiveness of SAP, which can achieve competitive performance with current action detection algorithms via much fewer proposals.

This code has been tested on Ubuntu 16.04 with NVIDIA Tesla K80. The CUDA version is 8.0.61
