Incorporating sparse labels into hidden Markov models using weighted likelihoods improves accuracy and interpretability in biologging studies

Autor: Sidrow, Evan, Heckman, Nancy, McRae, Tess M., Volpov, Beth L., Trites, Andrew W., Fortune, Sarah M. E., Auger-Méthé, Marie

Ecologists often use a hidden Markov model to decode a latent process, such as a sequence of an animal's behaviours, from an observed biologging time series. Modern technological devices such as video recorders and drones now allow researchers to dir

Variance-Reduced Stochastic Optimization for Efficient Inference of Hidden Markov Models

Autor: Sidrow, Evan, Heckman, Nancy, Bouchard-Côté, Alexandre, Fortune, Sarah M. E., Trites, Andrew W., Auger-Méthé, Marie

Hidden Markov models (HMMs) are popular models to identify a finite number of latent states from sequential data. However, fitting them to large data sets can be computationally demanding because most likelihood maximization techniques require iterat

Report

Modelling multi-scale state-switching functional data with hidden Markov models

Autor: Sidrow, Evan, Heckman, Nancy, Fortune, Sarah M. E., Trites, Andrew W., Murphy, Ian, Auger-Méthé, Marie

Publikováno v: Can J Statistics 50 (2022) 327-356

Data sets comprised of sequences of curves sampled at high frequencies in time are increasingly common in practice, but they can exhibit complicated dependence structures that cannot be modelled using common methods of Functional Data Analysis (FDA).
