Large Deviations for Hawkes Processes with Randomized Baseline Intensity

نویسندگان

چکیده

The Hawkes process, which is generally defined for the continuous-time setting, can be described as a self-exciting simple point process with clustering effect, whose jump rate depends on its entire history. Due to past events determining future developments of processes, model not Markovian. In certain special circumstances, it Markovian generator if exciting function an exponential or sum functions. case non-Markovian difficulties arise when intensity given by baseline and other terms that depend history compared standard Poisson process. It one main methods used studying dynamical properties general highly important credit risk studies. intensity, instrumental in model, usually deterministic cases. this paper, we consider linear where randomly defined, investigate asymptotic results large deviations principle newly model. processes randomized dealt have wide applications insurance, finance, queue theory, statistics.

Large Deviations for Markovian Nonlinear Hawkes Processes

In the 2007 paper, Bordenave and Torrisi [1] proves the large deviation principles for Poisson cluster processes and in particular, the linear Hawkes processes. In this paper, we prove first a large deviation principle for a special class of nonlinear Hawkes process, i.e. a Markovian Hawkes process with nonlinear rate and exponential exciting function, and then generalize it to get the result f...

Large deviations and applications for Markovian Hawkes processes with a large initial intensity

Hawkes process is a class of simple point processes that is self-exciting and has clustering effect. The intensity of this point process depends on its entire past history. It has wide applications in finance, insurance, neuroscience, social networks, criminology, seismology, and many other fields. In this paper, we study linear Hawkes process with an exponential kernel in the asymptotic regime...

Process-level Large Deviations for Nonlinear Hawkes Point Processes

In this paper, we prove a process-level, also known as level-3 large deviation principle for a very general class of simple point processes, i.e. nonlinear Hawkes process, with a rate function given by the process-level entropy, which has an explicit formula.

Hawkes Processes on Large Networks

We generalise the construction of multivariate Hawkes processes to a possibly infinite network of counting processes on a directed graph G. The process is constructed as the solution to a system of Poisson driven stochastic differential equations, for which we prove pathwise existence and uniqueness under some reasonable conditions. We next investigate how to approximate a standard N -dimension...

Multivariate Hawkes Processes for Large-Scale Inference

In this paper, we present a framework for fitting multivariate Hawkes processes for large-scale problems, both in the number of events in the observed history n and the number of event types d (i.e. dimensions). The proposed Scalable LowRank Hawkes Process (SLRHP) framework introduces a lowrank approximation of the kernel matrix that allows to perform the nonparametric learning of the d trigger...
