The Hawkes process, or otherwise known as the self-exciting process, is an extension of Poisson processes that aims to explain excitatory interactions (Hawkes,1971). What makes the term self-excitation worthy of its name is typically not the occurrence of the initial event, but the in-tensification of further events.

WebFeb 28, 2024 · Multivariate Hawkes Processes (MHPs) are an important class of temporal point processes that have enabled key advances in understanding and predicting social information systems. However, due … WebHawkes processes [6] can be used in a variety of applica-tions such as inferring granger causality [11], modeling patient records in smart health [18], and predicting online social ac-tivities [1]. For example, a multi-dimensional Hawkes process has been proposed by Zhou et al. [1] to learn the social event
