Markov Observation Models and Deepfakes

open access: yesMathematics
Herein, expanded Hidden Markov Models (HMMs) are considered as potential deepfake generation and detection tools. The most specific model is the HMM, while the most general is the pairwise Markov chain (PMC). In between, the Markov observation model (MOM)

Time series segmentation with shifting means hidden markov models [PDF]

open access: yesNonlinear Processes in Geophysics, 2006
We present a new family of hidden Markov models and apply these to the segmentation of hydrological and environmental time series. The proposed hidden Markov models have a discrete state space and their structure is inspired from the shifting means ...

Transmission Line Fault Classification Using Hidden Markov Models

open access: yesIEEE Access, 2019
The maintenance of power quality in electrical power systems depends on addressing the major disturbances that may arise during generation, transmission and distribution. Many studies aim to investigate these disturbances by analyzing the behavior of the

Constrained hidden Markov models for population-based haplotyping

open access: yesBMC Bioinformatics, 2007
Background Haplotype Reconstruction is the problem of resolving the hidden phase information in genotype data obtained from laboratory measurements. Solving this problem is an important intermediate step in gene association studies, which seek to uncover

Map representation using hidden markov models for mobile robot localization

open access: yesMATEC Web of Conferences, 2018
This paper describes a map representation and localization system for a mobile robot based on Hidden Markov Models. These models are used not only to find a region where a mobile robot is, but also they find the orientation that it has.

Introducing Busy Customer Portfolio Using Hidden Markov Model [PDF]

open access: yesIranian Journal of Management Studies, 2011
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.

Modelling reassurances of clinicians with hidden Markov models

open access: yesBMC Medical Research Methodology, 2019
Background A key element in the interaction between clinicians and patients with cancer is reassurance giving. Learning about the stochastic nature of reassurances as well as making inferential statements about the influence of covariates such as patient

Proper account of auto-correlations improves decoding performances of state-space (semi) Markov models

open access: yesPeer Community Journal
State-space models are widely used in ecology to infer hidden behaviors. This study develops an extensive numerical simulation-estimation experiment to evaluate the state decoding accuracy of four simple state-space models.
