WebThe simulation of a multivariate Hawkes process with exponential decays on a xed interval is similar to the univariate case, with only one extra step that decides which dimension an accepted point belongs to. By Proposition 2.1, given that a point is accepted at time s, it should be distributed to dimension mwith probability m(s)= P M m=1 WebInference and simulation of Hawkes processes, with both parametric and non-parametric estimation techniques and flexible tools for simulation. tick.linear_model Inference and simulation of linear models, including among others linear, logistic and Poisson regression, with a large set of penalization techniques and solvers. tick.robust

Webstacked Dirichlet-Hawkes process with inverse cluster frequency prior as a simple but effective solution for the task of short text clustering using temporal features in continuous time. Based on the classical formulation of the Dirichlet-Hawkes process, our model provides an elegant, theoretically grounded and interpretable solu- 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
