Efficient algorithms for training the parameters of hidden Markov models using stochastic expectation maximization (EM) training and Viterbi training

Algorithms for Molecular Biology, 2010
Background Hidden Markov models are widely employed by numerous bioinformatics programs used today. Applications range widely from comparative gene prediction to time-series analyses of micro-array data. The parameters of the underlying models need to be

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 ...

AccelerometerBehavior: R Package for Classifying Ungulate Behaviors Into Three States

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We provide an R package, AccelerometerBehavior, which facilitates the classification of acceleration data into behavioral states using field‐validated models for ungulates. Our package provides the supervised models so users do not need their own observation data for model training.

Adaptive decoding of convolutional codes [PDF]

Advances in Radio Science, 2007
Convolutional codes, which are frequently used as error correction codes in digital transmission systems, are generally decoded using the Viterbi Decoder. On the one hand the Viterbi Decoder is an optimum maximum likelihood decoder, i.e.
