Named Entity Recognition Model Based on k-best Viterbi Decoupling Knowledge Distillation [PDF]
Jisuanji kexue yu tansuoKnowledge distillation is a general approach to improve the performance of the named entity recognition (NER) models. However, the classical knowledge distillation loss functions are coupled, which leads to poor logit distillation.

Linking the Movement Behavior of the Laptev Sea Walrus to Sea Ice and Resource Dynamics
Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT The walrus subspecies inhabiting the Laptev Sea (Odobenus rosmarus divergens) remains one of the least studied walrus taxa and occurs in a region undergoing rapid environmental change driven by climate warming and increasing human activity. We conducted the first satellite telemetry study of walruses in this region, tracking 14 individuals ...

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Divergence coding for convolutional codes
MATEC Web of Conferences, 2017 In the paper we propose a new coding/decoding on the divergence principle. A new divergent multithreshold decoder (MTD) for convolutional self-orthogonal codes contains two threshold elements.

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.Using hidden Markov models (HMM) to analyze dynamic brain states from resting‐state fMRI, this study identifies opposing temporal dynamics in Parkinson's disease (PD) and progressive supranuclear palsy (PSP). PD patients show reduced fractional occupancy in unimodal networks, while PSP patients exhibit increased occupancy and prolonged duration in ...

Context‐Dependent Movement Responses of Large Carabids to Forest Gap Cuttings
Ecology and Evolution, Volume 16, Issue 9, September 2026.This study investigates the effects of forest management on the movement of ground beetles within an oak‐hornbeam forest in northern Hungary. We compared a closed‐canopy control stand with various small‐scale canopy gaps. To track movement and habitat use within these treatments, two carabid species, Carabus ullrichii and C.

The Viterbi algorithm and Markov noise memory [PDF]
IEEE Transactions on Information Theory, 2000 Summary: This work designs sequence detectors for channels with intersymbol interference and correlated (and/or signal-dependent) noise. We describe three major contributions. i) First, by modeling the noise as a finite-order Markov process, we derive the optimal maximum-likelihood sequence detector (MLSD) and the optimal maximum a posteriori (MAP ...
