Hawkes processes
WebThe Hawkes process, which is generally defined for the continuous-time setting, can be described as a self-exciting simple point process with a clustering effect, whose jump rate depends on its entire history. Due to past events determining future developments of self-exciting point processes, the Hawkes model is generally not Markovian. In certain … WebNov 26, 2024 · Hawkes Processes are a type of point process which models self-excitement among time events.
