Local Viterbi property in decoding
Information and Inference: A Journal of the IMA, 2023 Abstract The article studies the decoding problem (also known as the classification or the segmentation problem) with pairwise Markov models (PMMs). A PMM is a process where the observation process and the underlying state sequence form a two-dimensional Markov chain, a natural generalization of hidden Markov model.

Engineering Reports, Volume 7, Issue 10, October 2025.This study proposes CRIBC, an advanced Named Entity Recognition (NER) model tailored for Chinese medical text processing. By integrating Chinese‐RoBERTa‐WWM‐EXT with BiLSTM‐CRF and IDCNN, CRIBC enables more accurate entity extraction and knowledge representation.

Unified Neural Lexical Analysis Via Two‐Stage Span Tagging
CAAI Transactions on Intelligence Technology, Volume 10, Issue 4, Page 1254-1267, August 2025.ABSTRACT Lexical analysis is a fundamental task in natural language processing, which involves several subtasks, such as word segmentation (WS), part‐of‐speech (POS) tagging, and named entity recognition (NER). Recent works have shown that taking advantage of relatedness between these subtasks can be beneficial.

Review and Analysis of Digital Signal Processing Algorithms for Coherent Optical Satellite Links
International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 229-250, May/June 2025.ABSTRACT Coherent optical satellite links enable high‐throughput communication and high accuracy ranging to and between satellites. Due to the ever‐increasing demand for throughput, wavelength division multiplexing of polarization multiplexed optical signals is being considered as a solution to provide high‐speed optical satellite links.

A Novel High-Speed Configurable Viterbi Decoder for Broadband Access
EURASIP Journal on Advances in Signal Processing, 2003 A novel design and implementation of an online reconfigurable Viterbi decoder is proposed, based on an area-efficient add-compare-select (ACS) architecture, in which the constraint length and traceback depth can be dynamically reconfigured.

Improved order selection method for hidden Markov models: A case study with movement data
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1215-1227, June 2025.Abstract Hidden Markov models (HMMs) are a versatile statistical framework commonly used in ecology to characterize behavioural patterns from animal movement data. In HMMs, the observed data depend on a finite number of underlying hidden states, generally interpreted as the animal's unobserved behaviour. The number of states is a crucial hyperparameter,
