Heavy tailed hidden semi-markov models [PDF]

open access: yesCommunications in Statistics. Stochastic Models, 1998
Summary: Hidden semi-Markov models have been proposed by \textit{K. S. Meier-Hellstern}, \textit{P. E. Wirth}, \textit{Y. L. Yan} and \textit{D. A. Hoeflin} [in: Teletraffic and datatraffic in a period of change (A. Jensen and V. B. Iversen (eds.)), 167-192 (1991)] to model the times between transmission of packets at a source.

Hidden Semi-Markov Models for Predictive Maintenance [PDF]

open access: yesMathematical Problems in Engineering, 2015
Realistic predictive maintenance approaches are essential for condition monitoring and predictive maintenance of industrial machines. In this work, we propose Hidden Semi-Markov Models (HSMMs) with (i) no constraints on the state duration density function and (ii) being applied to continuous or discrete observation. To deal with such a type of HSMM, we

A Regularized Vector Autoregressive Hidden Semi-Markov model, with Application to Multivariate Financial Data

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2021
Hidden Markov model (HMM) has been a popular choice for financial time series modeling due to its advantage in capturing dynamic regimes. However, HMM's implicit assumption that the state duration follows a geometric distribution is too strong to hold in

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 ...

Target Location Method Based on Compressed Sensing in Hidden Semi Markov Model

open access: yesElectronics, 2022
A compressive sensing-based target localization method based on hidden semi-Markov model (HsMM) is proposed to address problems like unpredictable data and the multipath effect of the Receive Signal Strength (RSS) in indoor localization.

Hidden Markov models: the best models for forager movements? [PDF]

open access: yesPLoS ONE, 2013
One major challenge in the emerging field of movement ecology is the inference of behavioural modes from movement patterns. This has been mainly addressed through Hidden Markov models (HMMs).

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

Flexible and practical modeling of animal telemetry data: hidden Markov models and extensions [PDF]

open access: yes, 2012
We discuss hidden Markov-type models for fitting a variety of multistate random walks to wildlife movement data. Discrete-time hidden Markov models (HMMs) achieve considerable computational gains by focusing on observations that are regularly spaced in ...
