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.

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 ...
