Hidden Semi-Markov Models-Based Visual Perceptual State Recognition for Pilots [PDF]

open access: goldSensors, 2023
Pilots’ loss of situational awareness is one of the human factors affecting aviation safety. Numerous studies have shown that pilot perception errors are one of the main reasons for a lack of situational awareness without a proper system to detect these ...

Semi-Markov and hidden semi-Markov models of energy systems [PDF]

open access: diamondE3S Web of Conferences, 2018
The problem of information control systems creation for energy systems and transition to intelligent control and engineering is one of the important problems of reliability and efficiency theory for energy systems. The solution of this problem is possible based on construction of mathematical models concerning different aspects of these systems ...

biomvRhsmm: genomic segmentation with hidden semi-Markov model. [PDF]

open access: yesBiomed Res Int, 2014
High-throughput technologies like tiling array and next-generation sequencing (NGS) generate continuous homogeneous segments or signal peaks in the genome that represent transcripts and transcript variants (transcript mapping and quantification), regions of deletion and amplification (copy number variation), or regions characterized by particular ...

Labeling self-tracked menstrual health records with hidden semi-Markov models [PDF]

open access: goldIEEE Journal of Biomedical and Health Informatics, 2021
AbstractGlobally, millions of women track their menstrual cycle and fertility via smartphone-based health apps, generating multivariate time series with frequent missing data. To leverage data from self-tracking tools in epidemiological studies on fertility or the menstrual cycle’s effects on diseases and symptoms, it is critical to have methods for ...

Bayesian Nonparametric Hidden Semi-Markov Models [PDF]

open access: green, 2012
There is much interest in the Hierarchical Dirichlet Process Hidden Markov Model (HDP-HMM) as a natural Bayesian nonparametric extension of the ubiquitous Hidden Markov Model for learning from sequential and time-series data. However, in many settings the HDP-HMM's strict Markovian constraints are undesirable, particularly if we wish to learn or encode

Hidden Semi-Markov Models for Predictive Maintenance [PDF]

open access: hybridMathematical 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

Hidden semi-Markov models to segment reading phases from eye movements

open access: goldJournal of Eye Movement Research, 2022
Our objective is to analyze scanpaths acquired through participants achieving a reading task aiming at answering a binary question: Is the text related or not to some given target topic? We propose a data-driven method based on hidden semi-Markov chains to segment scanpaths into phases deduced from the model states, which are shown to represent ...

A hidden semi-Markov model for estimating burst suppression EEG. [PDF]

open access: yesAnnu Int Conf IEEE Eng Med Biol Soc, 2019
Burst suppression is an electroencephalogram (EEG) pattern associated with profoundly inactivated brain states characterized by cerebral metabolic depression. This pattern is distinguished by short-duration band-limited electrical activity (bursts) interspersed between relatively near-isoelectric periods (suppressions).

The Hierarchical Dirichlet Process Hidden Semi-Markov Model [PDF]

open access: green, 2012
There is much interest in the Hierarchical Dirichlet Process Hidden Markov Model (HDP-HMM) as a natural Bayesian nonparametric extension of the traditional HMM. However, in many settings the HDP-HMM's strict Markovian constraints are undesirable, particularly if we wish to learn or encode non-geometric state durations.
