Imprecise continuous-time Markov chains

open access: yesInternational Journal of Approximate Reasoning, 2017
Continuous-time Markov chains are mathematical models that are used to describe the state-evolution of dynamical systems under stochastic uncertainty, and have found widespread applications in various fields. In order to make these models computationally tractable, they rely on a number of assumptions that may not be realistic for the domain of ...

Entropy rate of continuous-state hidden Markov chains [PDF]

open access: yes, 2010
We prove that under mild positivity assumptions, the entropy rate of a continuous-state hidden Markov chain, observed when passing a finite-state Markov chain through a discrete-time continuous-output channel, is analytic as a function of the transition ...

Event-Chain Monte Carlo: Foundations, Applications, and Prospects

open access: yesFrontiers in Physics, 2021
This review treats the mathematical and algorithmic foundations of non-reversible Markov chains in the context of event-chain Monte Carlo (ECMC), a continuous-time lifted Markov chain that employs the factorized Metropolis algorithm. It analyzes a number

Fast-slow asymptotics for a Markov chain model of fast sodium current [PDF]

open access: yes, 2017
We explore the feasibility of using fast-slow asymptotic to eliminate the computational stiffness of the discrete-state, continuous-time deterministic Markov chain models of ionic channels underlying cardiac excitability. We focus on a Markov chain model

A continuous-time Markov chain and stochastic differential equations approach for modeling malaria propagation

open access: yesHealthcare Analytics, 2023
Malaria is the world’s most fatal and challenging parasitic disease, caused by the Plasmodium parasite and transmitted to humans by the bites of infected female mosquitos.

Finding a marked node on any graph by continuous-time quantum walk

open access: yes, 2020
Spatial search by discrete-time quantum walk can find a marked node on any ergodic, reversible Markov chain $P$ quadratically faster than its classical counterpart, i.e.\ in a time that is in the square root of the hitting time of $P$.

Analyzing the profit-loss sharing contracts with Markov model

open access: yesCommunications in Science and Technology, 2016
The purpose of this paper is to examine how to use first order Markov chain to build a reliable monitoring system for the profit-loss sharing based contracts (PLS) as the mode of financing contracts in Islamic bank with censored continuous-time ...

Numerical Computation of Distributions in Finite-State Inhomogeneous Continuous Time Markov Chains, Based on Ergodicity Bounds and Piecewise Constant Approximation

open access: yesMathematics, 2023
In this paper it is shown, that if a possibly inhomogeneous Markov chain with continuous time and finite state space is weakly ergodic and all the entries of its intensity matrix are locally integrable, then, using available results from the perturbation

Generalized Markov stability of network communities

open access: yes, 2020
We address the problem of community detection in networks by introducing a general definition of Markov stability, based on the difference between the probability fluxes of a Markov chain on the network at different time scales.
