Hidden Markov Models

Introduction to Computational Thinking, 2021
Some temporal patterns are difficult to detect, and to learn, because they are hidden: only indirect clues are telling us what is going on under the surface. Problems of this kind fall under the rubric of Hidden Markov Models, HMM.

Hidden Markov models

2001
We divide this brief account of hidden Markov models into three sections: (i) a description of the properties of these models, (ii) the three main algorithms of the models, (iii) applications. For a more complete account of these models, see Rabiner (1989).

Real-Time Multistep Attack Prediction Based on Hidden Markov Models

IEEE Transactions on Dependable and Secure Computing, 2020
A novel method based on the Hidden Markov Model is proposed to predict multistep attacks using IDS alerts. We consider the hidden states as similar phases of a particular type of attack.

Hidden Markov models

Current Opinion in Structural Biology, 1996
'Profiles' of protein structures and sequence alignments can detect subtle homologies. Profile analysis has been put on firmer mathematical ground by the introduction of hidden Markov model (HMM) methods. During the past year, applications of these powerful new HMM-based profiles have begun to appear in the fields of protein-structure prediction and ...

Hidden Markov Models

2011
Hidden Markov models (HMMs) are important in pattern recognition because they are ideally suited to classify patterns where each pattern is made up of a sequence of sub-patterns. For example, assume that a day is either sunny, cloudy, or rainy corresponding to three different types of weather conditions.

Revisiting Hidden Markov Models for Speech Emotion Recognition

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2019
Hidden Markov models (HMMs) have a long tradition in automatic speech recognition (ASR) due to their capability of capturing temporal dynamic characteristics of speech.

Hidden Markov Models

2010
This book build upon the use of Hidden Markov Models as motion models, which, as we have seen in chapter 3, are probably the most popular technique for pattern based motion prediction. This chapter provides the reader with a broad introduction to this probabilistic framework.
