Hidden semi-Markov models

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...

Speaker Independent Speech Recognition Using Hidden Markov Models for Persian Isolated Words

Microsoft Word - Hybridmodel2.dot

Today’s state-of-the-art speech recognition systems typically use continuous density hidden Markov models with mixture of Gaussian distributions. Such speech recognition systems have problems; they require too much memory to run, and are too slow for large vocabulary applications. Two approaches are proposed for the design of compact acoustic models, namely, subspace distribution clustering hid...

Markov Models for Automated ECG Interval Analysis

We examine the use of hidden Markov and hidden semi-Markov models for automatically segmenting an electrocardiogram waveform into its constituent waveform features. An undecimated wavelet transform is used to generate an overcomplete representation of the signal that is more appropriate for subsequent modelling. We show that the state durations implicit in a standard hidden Markov model are ill...

Modelling Duration in Activity Recognition using Generative and Discriminative Models

Human activity recognition allows many applications in areas such as intelligent environments and health monitoring. Typically probabilistic models such as the hidden Markov model or conditional random fields are used to map the observed sensor data onto the hidden activity states. A weakness of these models, however, is their inaccurate modelling of state durations. Hidden semi-Markov models a...
