AbstractGroup activity classification is the task to identify activities with multiple person participation, which often involves in the usage of the context information like person relationships and person interactions. In this paper, we propose a novel approach to jointly model three co-existing cues including the activity duration time, individual action feature and the context information shared between person interactions. Our approach infers group activity labels of all the persons together with their activity durations, especially for the situation with multiple group activities co-existing. Experimental results show that our approach outperform state-of-the-art by 10%.
