Electronics Letters, Volume 62, Issue 1, January/December 2026.This paper proposes a collaborative 3D parameter inversion method for processing cones using a cross‐view dual‐stream BiGRU (CV‐DS‐BiGRU) network and spatial geometric decoupling. ABSTRACT Traditional radar micro‐Doppler (m‐D) feature extraction suffers from single‐station occlusion and noise, while end‐to‐end (E2E) deep learning lacks physical ...

A Novel Entropy-Based Decoding Algorithm for a Generalized High-Order Discrete Hidden Markov Model
Journal of Probability and Statistics, 2018 The optimal state sequence of a generalized High-Order Hidden Markov Model (HHMM) is tracked from a given observational sequence using the classical Viterbi algorithm. This classical algorithm is based on maximum likelihood criterion.

Estimating Environmental Transmission Risk From Host Movement Data
Ecology and Evolution, Volume 15, Issue 12, December 2025.We present a comparative modeling framework that integrates host movement, pathogen persistence, and behavior to quantify environmentally mediated transmission. Using wild pig GPS data and SEIR simulations, we show that contact definitions significantly alter transmission dynamics, highlighting the importance of mechanistically defining indirect ...

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