Web1 dec. 2012 · These compound processes are likely to be useful: compound Markov counting processes have been found to give better DNA sequence alignments from genomic data, in the context of insertion–deletion models (Thorne et al., 1992), and to improve the likelihood of infectious disease data, in the context of … WebThe method is developed by considering counting processes associated with events that are determined by the states at two successive renewals of a Markov renewal process, for which it both simplifies and generalises existing results. More explicit results are given in the case of an underlying continuous-time Markov chain.

WebCount sketch is a type of dimensionality reduction that is particularly efficient in statistics, machine learning and algorithms. It was invented by Moses Charikar, Kevin Chen and Martin Farach-Colton in an effort to speed up the AMS Sketch by Alon, Matias and Szegedy for approximating the frequency moments of streams.. The sketch is nearly identical to … WebCounting processes deal with the number of occurrences of something over time. An example of a counting process is the number of job arrivals to a queue over time. If a process has the Markov property , it is said to be a Markov counting process. courtyard stone hilton headWebMarkov models and MMPPs are commonly deployed in traffic modeling and queuing theory. They allow for analytically tractable results for many use cases [10, 21].MMPP models consist of a Poisson process modulated by the rate λ i [k], which is determined by the state of a Markov chain s n [k].Thereby, k denotes the time index, obtained by migrating from … courtyard st louis brentwood

Web1 sep. 2003 · A non-Markovian counting process, the ‘generalized fractional Poisson process’ (GFPP) introduced by Cahoy and Polito in 2013 is analyzed. The GFPP contains two index parameters 0 < β ≤ 1, α > 0 and a time scale parameter.
