Recent Trends in Activity Recognition

讲座内容:

Abstract: Twoof our new attempts in combining deep learning with human activity recognitionwill be introduced in this talk. (1) Wi-Fi channel state information (CSI)provides adequate information for recognizing and analyzing human activities.Traditional Wi-Fi CSI based human activity recognition methods adopt Wi-Fi CSIfrom a single AP, which is not so appropriate for a high-density Wi-Fi environment.In this work, we propose a learning method that analyzes the CSI of multipleAPs in a small area to detect and recognize human activities. We introduce adeep learning model to process complex and large CSI information from multipleAPs. From extensive experiment results, our method performs better than othersolutions in a given environment where multiple Wi-Fi APs exist. (2) Thepostures of the same activity performed by different persons may not be thesame exactly. This phenomenon makes it hard to explore a robust activitydescription based on postures. In order to better address the individualdiversity, we propose a skeletal point based concept denoted as ActivityContribution Degree (ACD), which indicates the information contribution levelof the skeletal point. Since the ACD variation of the skeletal point is morestable than postures, we can get a more robust activity description. Theexperimental results show that our model can achieve higher recognitionaccuracy.
