WebThe concept of Gaussian processes is named after Carl Friedrich Gauss because it is based on the notion of the Gaussian distribution ( normal distribution ). Gaussian processes can be seen as an infinite-dimensional generalization of multivariate normal distributions. WebIn probability theory and statistics, a Hawkes process, named after Alan G. Hawkes, is a kind of self-exciting point process.[1] It has arrivals at times 0<⋯{\textstyle 0<\cdots }where the infinitesimal probability of an arrival during the time interval [t,t+dt){\textstyle [t,t+dt)}is
