A Novel Method for Decoding Any High-Order Hidden Markov Model

open access: yesDiscrete Dynamics in Nature and Society, 2014
This paper proposes a novel method for decoding any high-order hidden Markov model. First, the high-order hidden Markov model is transformed into an equivalent first-order hidden Markov model by Hadar’s transformation. Next, the optimal state sequence of

Research on HMM based link prediction method in heterogeneous network

open access: yesTongxin xuebao, 2022
In order to solve the problem that incomplete mining of structural information and semantic information in heterogeneous networks, a link prediction method combining meta-path-based analysis and hidden Markov model was proposed for link prediction of ...

The Application of Baum-Welch Algorithm in Multistep Attack

open access: yesThe Scientific World Journal, 2014
The biggest difficulty of hidden Markov model applied to multistep attack is the determination of observations. Now the research of the determination of observations is still lacking, and it shows a certain degree of subjectivity.

fHMM: Hidden Markov Models for Financial Time Series in R

open access: yesJournal of Statistical Software
Hidden Markov models constitute a versatile class of statistical models for time series that are driven by hidden states. In financial applications, the hidden states can often be linked to market regimes such as bearish and bullish markets or ...

Hidden Markov Model Based on Logistic Regression

open access: yesMathematics, 2023
A hidden Markov model (HMM) is a useful tool for modeling dependent heterogeneous phenomena. It can be used to find factors that affect real-world events, even when those factors cannot be directly observed.
