The fine-grained behavior modeling framework consists of the subject correlation layer, behavior sequence layer, and attribute distribution layer. The subject correlation layer reflects the association between subjects and is coupled with a mapping relationship to the behavior sequence layer. There is a time-annotated edge with time information T = (to, td) between each subject and behavior, where time T indicates the starting time to and ending time td when the subject initiates the behavior. In the behavior sequence layer, different behaviors occur in a clear sequence, and we denote Δt = σ(T1, T2) as the time difference between two behaviors T1 and T2. A behavior is described in detail by several attributes, and their associations are reflected as the coupling mapping between the behavior sequence layer and the attribute distribution layer
