Finite-Time Asynchronous H_∞ Control for Non-Homogeneous Hidden Semi-Markov Jump Systems

Mathematics
This article explores the finite-time control problem associated with a specific category of non-homogeneous hidden semi-Markov jump systems. Firstly, a hidden semi-Markov model is designed to characterize the asynchronous interactions that occur between

DQN‐Guided Subset‐Induced OCSVM Kernel Approximation for Imbalanced Anomaly Detection

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Anomaly detection under limited normal data remains a fundamental challenge due to severe class imbalance and scarcity of anomalies. We propose a novel framework that reformulates support vector selection in One‐Class SVM as a sequential decision‐making problem.

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds

Journal of Animal Ecology, EarlyView.
Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...

A Logical Hierarchical Hidden Semi-Markov Model for Team Intention Recognition

Discrete Dynamics in Nature and Society, 2015
Intention recognition is significant in many applications. In this paper, we focus on team intention recognition, which identifies the intention of each team member and the team working mode.

Emotional and motivational experiences in teacher–student relationships and psychological need satisfaction during adolescence: A latent profile and latent transition analysis

British Journal of Educational Psychology, EarlyView.
Abstract Background Emotional and motivational aspects of teacher–student relationships are central to adolescents' psychological need satisfaction and academic development. However, few longitudinal studies examine how these relational experiences evolve during adolescence or co‐occur with emotional‐motivational functioning.

hmmTMB: Hidden Markov Models with Flexible Covariate Effects in R

Journal of Statistical Software
Hidden Markov models (HMMs) are widely applied in studies where a discrete-valued process of interest is observed indirectly. They have for example been used to model behavior from human and animal tracking data, disease status from medical data, and ...

Automatic Harmonization Using a Hidden Semi-Markov Model

Proceedings of the AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment, 2013
Hidden Markov Models have been used frequently in the audio domain to identify underlying musical structure. Much less work has been done in the purely symbolic realm. Recently, a substantial amount of expert-labelled symbolic musical data has been injected into the research community.

Evaluating the CDMA System Using Hidden Markov and Semi Hidden Markov Models

, 2021
CDMA is an important and basic part of today’s communications technologies. This technology can be analyzed efficiently by reducing the time, computation burden, and cost by characterizing the physical layer with a Markov Model. Waveform level simulation

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Equivalence and Reduction of Hidden Markov Models [PDF]

, 1993
This report studies when and why two Hidden Markov Models (HMMs) may represent the same stochastic process. HMMs are characterized in terms of equivalence classes whose elements represent identical stochastic processes. This characterization yields
