Mixed Markov models [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
Markov random fields can encode complex probabilistic relationships involving multiple variables and admit efficient procedures for probabilistic inference. However, from a knowledge engineering point of view, these models suffer from a serious limitation.

Bayesian Model Selection for Markov, Hidden Markov, and Multinomial Models [PDF]

open access: yesIEEE Signal Processing Letters, 2007
Model selection based on observed data sequences is used to decide between different model structures within the class of multinomial, Markov, and hidden Markov models. In a unified Bayesian treatment, we derive posterior probabilities for different model structures without assuming prior knowledge of transition probabilities.

Cost-Effectiveness Mathematical Model to Evaluate the Impact of Improved Cardiac Ablation Strategies for Atrial Fibrillation Treatment

open access: yesMathematics, 2023
Atrial fibrillation (AF) is the most common form of cardiac arrhythmia. Despite the frequency of the disease, the treatment strategies for AF are inefficient.

Exploratory search during directed navigation in C. elegans and Drosophila larva

open access: yeseLife, 2017
Many organisms—from bacteria to nematodes to insect larvae—navigate their environments by biasing random movements. In these organisms, navigation in isotropic environments can be characterized as an essentially diffusive and undirected process.

Methodology for Evaluating the Impact of Sudden Failures on the Reliability Parameters of the Optical Cable Damaged Section

open access: yesProceedings of the International Conference on Applied Innovations in IT, 2023
An optical cable is considered as a multicomponent system, which components are elementary sections of an optical cable. During operation, due to failures of these sections, they are replaced with new ones.
