The hidden Markov chain modelling of the COVID-19 spreading using Moroccan dataset [PDF]

open access: yesData in Brief, 2020
The World Health Organization (WHO) declared in March 12, 2020 the COVID-19 disease as pandemic. In Morocco, the first local transmission case was detected in March 13.

Ergodicity and regime recoverability in finite Markov-modulated random walks [PDF]

open access: yesScientific Reports
We study a finite Markov-modulated random walk (MMRW) on a one-dimensional lattice with reflecting boundaries, where a hidden finite-state Markov environment $$E_t$$ selects at each time step a regime-specific random walk kernel for the position process $

ToPS: a framework to manipulate probabilistic models of sequence data. [PDF]

open access: yesPLoS Computational Biology, 2013
Discrete Markovian models can be used to characterize patterns in sequences of values and have many applications in biological sequence analysis, including gene prediction, CpG island detection, alignment, and protein profiling.

A Sticky Sampling and Markov State Transition Matrix Based Driving Cycle Construction Method for EV

open access: yesEnergies, 2022
Driving cycle (DC) plays an important role in designing and evaluating EVs, and many Markov chain-based DC construction methods describe driving profiles of unfixed-line vehicles with Markov state transition probability.

Toward Efficient Bayesian Approaches to Inference in Hierarchical Hidden Markov Models for Inferring Animal Behavior

open access: yesFrontiers in Ecology and Evolution, 2021
The study of animal behavioral states inferred through hidden Markov models and similar state switching models has seen a significant increase in popularity in recent years.

A Unified Framework for Fault Detection and Diagnosis Using Particle Filter [PDF]

open access: yesModeling, Identification and Control, 2014
In this paper, a particle filter (PF) based fault detection and diagnosis framework is proposed. A system with possible faults is modeled as a group of hidden Markov models representing the system in fault-free mode and different failure modes, and a ...

From Risk Assessment to Resilience Assessment. an Application to a Hazmat Storage Plant

open access: yesChemical Engineering Transactions, 2020
The purpose of this work is to outline a framework for assessing the resilience of a petrochemical storage plant, through the construction of a dynamic hierarchical Bayesian network. The BN approach allows keeping memory of the states, in order to manage

THE APPLICATION OF DISCRETE HIDDEN MARKOV MODEL ON CROSSES OF DIPLOID PLANT

open access: yesBarekeng, 2023
The hidden Markov model consists of a pair of an unobserved Markov chain {Xk} and an observation process {Yk}. In this research, the crosses of diploid plant apply the model.

Prediksi Kurs Rupiah Terhadap Dolar Dengan FTS-Markov Chain Dan Hidden Markov Model

open access: yesJurnal Derivat, 2019
Hidden Markov model is a development of the Markov chain where the state cannot be observed directly (hidden), but can only be observed, a set of other observations and combination of fuzzy logic and Markov chain to predict Rupiah exchange rate against ...

Modelling and Prediction of Random Delays in NCSs Using Double-Chain HMMs

open access: yesDiscrete Dynamics in Nature and Society, 2020
This paper is concerned with the modelling and prediction of random delays in networked control systems. The stochastic distribution of the random delay in the current sampling period is assumed to be affected by the network state in the current sampling
