Population viewpoint on Hawkes processes

Alexandre Boumezoued
2016 Advances in Applied Probability  
In this paper we focus on a class of linear Hawkes processes with general immigrants. These are counting processes with shot-noise intensity, including self-excited and externally excited patterns.  ...  The pathwise construction of the Hawkes process and its underlying population is also given.  ...  Population viewpoint on Hawkes processes 475 Proposition 2.  ...

Managing process inconsistency using viewpoints

I. Sommerville, P. Sawyer, S. Viller
1999 IEEE Transactions on Software Engineering  
We present a description and rationale of process viewpoints, discuss the process of applying process viewpoints for process understanding and illustrate the overall approach using part of a case study  ...  By analogy with viewpoints for requirements engineering that allow multiple perspectives on a software system specification to be managed, we have developed the notion of process viewpoints that provide  ...  Figure 1 A process viewpoint We must emphasise that process viewpoints are not projections of some underlying, definitive process and that merging the process descriptions in the different process viewpoints  ...

Population viewpoint on Hawkes processes [article]

2015 arXiv   pre-print
This paper focuses on a class of linear Hawkes processes with general immigrants. These are counting processes with shot noise intensity, including self-excited and externally excited patterns.  ...  The pathwise construction of the Hawkes process and its underlying population is also given.  ...  In fact, this age pyramid process, that is the measure-valued process (Z t (da)) t≥0 , is a Markov process (see Tran (2006) ).  ...

Revisiting queueing output processes: a point process viewpoint

D. J. Daley
2011 Queueing systems  
A standard integral formula for the variance of a stationary orderly point process shows that, if N dep is a renewal process whose generic lifetime X has finite second moment, then B 1 = (var X)/ ([E(X  ...  It is conjectured that var N(0, t] ∼ B 1 t for any stationary point process N possessing an embedded regenerative structure.  ...  M/M/k/K revisited There is another, more enlightening, viewpoint to be discerned from recalling that a 'simple' queueing system involves two point processes, one for arrivals and one for service times,  ...

The regular viewpoint on PA-processes [chapter]

D. Lugiez, Ph. Schnoebelen
1998 Lecture Notes in Computer Science  
PA is the process algebra allowing non-determinism, sequential and parallel compositions, and recursion.  ...  We suggest viewing PA-processes as trees, and using treeautomata techniques for verification problems on PA.  ...  The tree-automata viewpoint has many advantages. It gives simpler and more general proofs. It helps one to understand why some problems can be solved in P-time, some others in NP-time, etc.  ...

A Logical Viewpoint on Process-Algebraic Quotients [chapter]

Antonín Kučera, Javier Esparza
1999 Lecture Notes in Computer Science  
To see that even an infinite-state process can have a very small § § -characterization, consider the process W of Fig. 1. The process I is a § § , and the process is the § § -characterization of W .  ...  Such processes must exist by Lemma 7.  ...

Duality in stochastic processes from the viewpoint of basis expansions [article]

Jun Ohkubo, Yuuki Arai
2019 arXiv   pre-print
The viewpoint of basis expansions enables us to obtain various dual stochastic processes. As a demonstration, dual processes based on Taylor-type and Hermite polynomials are derived.  ...  A new derivation method of duality relations in stochastic processes is proposed. The current focus is on the duality between stochastic differential equations and birth-death processes.  ...  The viewpoint is based on the basis expansion, which enables us to obtain various dual stochastic processes naturally.  ...
