%description
Implements the methodology introduced in Capezza, Lepore, and Paynabar
(2025) <doi:10.1080/00401706.2025.2561744> for process monitoring with
limited labeling resources. The package provides functions to (i) simulate
data streams with true latent states and multivariate Gaussian
observations as done in the paper, (ii) fit partially hidden Markov models
(pHMMs) using a constrained Baum-Welch algorithm with partial labels, and
(iii) perform stream-based active learning that balances exploration and
exploitation to decide whether to request labels in real time. The
methodology is particularly suited for statistical process monitoring in
industrial applications where labeling is costly.
