A Causality-Aware Pattern Mining Scheme for Group Activity Recognition in a Pervasive Sensor Space

no code implementations1 Dec 2023 Hyunju Kim, Heesuk Son, Dongman Lee

In this paper, we focus on a group activity by which a group of users perform a collaborative task without user identification and propose an efficient group activity recognition scheme which extracts causality patterns from pervasive sensor event sequences generated by a group of users to support as good recognition accuracy as the state-of-the-art graphical model.
