Prediction of PM2.5 pollution in Tehran air based on temperature and pressure using Markovian regime-switching non-parametric additive transitive regression model [PDF]

open access: yesریاضی و جامعه, 2023
In this paper, we introduce the Markovian regime-switching regression model, which is a graphical model based on the hidden Markov model. This model can be viewed as a clustered regression model, in which a Markov process models the transition from one ...

Development and analysis of models for service migration to the MEC server based on hysteresis approach

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2022
Online video services are among the most popular ways of content consumption. Video hosting servers have a very high load every day, which we propose to reduce by migrating the application with the video content in demand to the local Multi-access Edge ...

Markov genealogy processes

open access: yesTheoretical Population Biology, 2022
We construct a family of genealogy-valued Markov processes that are induced by a continuous-time Markov population process. We derive exact expressions for the likelihood of a given genealogy conditional on the history of the underlying population process.
