Notes on Hidden Markov Models

چکیده

A Markov model, or Markov chain, can be viewed as a stochastic finite state automaton in which each transition is labeled with a probability in such a way that the set of transitions from a given state have their probability labels adding up to 1. If in addition each state is labeled with an observable symbol, the probability of a string of symbols [x1, x2, ..., xn] (abbreviated as x1,n) is the product of the probabilities of successive transitions (starting in state x0, an arbitrary label for the string beginning).

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...

Scale- and Rhythm-Aware Musical Note Estimation for Vocal F0 Trajectories Based on a Semi-Tatum-Synchronous Hierarchical Hidden Semi-Markov Model

This paper presents a statistical method that estimates a sequence of musical notes from a vocal F0 trajectory. Since the onset times and F0s of sung notes are considerably deviated from the discrete tatums and pitches indicated in a musical score, a score model is crucial for improving timefrequency quantization of the F0s. We thus propose a hierarchical hidden semi-Markov model (HHSMM) that c...

Features Extraction for Music Notes Recognition using Hidden Markov Models

In recent years Hidden Markov Models (HMMs) have been successfully applied to human speech recognition. The present article proves that this technique is also valid to detect musical characteristics, for example: musical notes. However, any recognition system needs to get a suitable set of parameters, that is, a reduced set of magnitudes that represent the outstanding aspects to classify an ent...
