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.

Optimal detection and error exponents for hidden semi-Markov models [PDF]

open access: yesIEEE Journal of Selected Topics in Signal Processing, 2018
We study detection of random signals corrupted by noise that over time switch their values (states) between a finite set of possible values, where the switchings occur at unknown points in time. We model such signals as hidden semi-Markov signals (HSMS),

Decoding Chinese stock market returns: three-state hidden semi-Markov model [PDF]

open access: yesPacific-Basin Finance Journal, 2017
In this paper, we employ a three-state hidden semi-Markov model (HSMM) to explain the time-varying distribution of the Chinese stock market returns since 2005.

The Effects of Mindfulness on Brain Network Dynamics Following an Acute Stressor in a Population of Drinking Adults [PDF]

open access: yesBrain Sciences
Background: Previous research has found that mindfulness-based techniques are beneficial for reducing stress in heavy-drinking individuals. However, the underlying neurobiology of these stress-reducing effects are unclear.

Feature Selection for Hidden Markov Models and Hidden Semi-Markov Models

open access: yesIEEE Access, 2016
In this paper, a joint feature selection and parameter estimation algorithm is presented for hidden Markov models (HMMs) and hidden semi-Markov models (HSMMs).

Automatic Harmonization Using a Hidden Semi-Markov Model

open access: bronzeProceedings of the AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment, 2013
Hidden Markov Models have been used frequently in the audio domain to identify underlying musical structure. Much less work has been done in the purely symbolic realm. Recently, a substantial amount of expert-labelled symbolic musical data has been injected into the research community.

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.
