Hidden Markov Models with Mixed States

نویسنده

  • Andrew M. Fraser
چکیده

We note similarities of the state space reconstruction (\Embedology") practiced in numerical work on chaos, state space methods of stochastic systems theory, and the hidden Markov models (HMMs) used in speech research. We review Baum's EM algorithm in general and the speciic forward-backward algorithm that optimizes a class of HMM that has a mixed state space consisting of continuous and discrete parts. We then describe forecasts based on models t to data set D.

Introducing Busy Customer Portfolio Using Hidden Markov Model

Due to the effective role of Markov models in customer relationship management (CRM), there is a lack of comprehensive literature review which contains all related literatures. In this paper the focus is on academic databases to find all the articles that had been published in 2011 and earlier. One hundred articles were identified and reviewed to find direct relevance for applying Markov models...

An Adaptive Approach to Increase Accuracy of Forward Algorithm for Solving Evaluation Problems on Unstable Statistical Data Set

Nowadays, Hidden Markov models are extensively utilized for modeling stochastic processes. These models help researchers establish and implement the desired theoretical foundations using Markov algorithms such as Forward one. however, Using Stability hypothesis and the mean statistic for determining the values of Markov functions on unstable statistical data set has led to a significant reducti...

INFERENCE IN MIXED HIDDEN MARKOV MODELS AND APPLICATIONS TO MEDICAL STUDIES by

— The aim of the present paper is to document the need for adapting the definition of hidden Markov models (HMM) to population studies, which rigorous interpretation typically requires the use of mixed-effects models, as well as for corresponding learning methodologies. In this article, mixed hidden Markov models (MHMM) are introduced through a brief state of the art on hidden Markov models and...
