DOI: 10.1002/sim.8977
Abstract: Hidden Markov models (HMMs) have been proposed to model the natural history of diseases while accounting for misclassification in state identification. We introduce a discrete time HMM for human papillomavirus (HPV) and cervical precancer/cancer where… read more here.

DOI: 10.1007/s11222-018-9827-1
Abstract: We present an importance sampling algorithm that can produce realisations of Markovian epidemic models that exactly match observations, taken to be the number of a single event type over a period of time. The importance… read more here.

DOI: 10.1016/j.jmaa.2018.10.026
Abstract: Abstract This article focuses on a partially observed linear diffusion with jumps described by a Poisson process. Precisely, we study an inferential problem for the intensity of the Poisson process by establishing a moderate deviation… read more here.

DOI: 10.1016/j.neucom.2017.05.004
Abstract: Abstract Recognizing activities from behavior data is important for comprehensively understanding human’s intents and interests. However, in most cases, the user behaviors are partially observed or recorded, which make it a big challenge to model… read more here.

DOI: 10.1063/5.0019309
Abstract: This paper addresses the data-driven identification of latent representations of partially observed dynamical systems, i.e., dynamical systems for which some components are never observed, with an emphasis on forecasting applications and long-term asymptotic patterns. Whereas… read more here.

DOI: 10.1080/00224065.2023.2282512
Abstract: Abstract Image-based monitoring techniques have achieved great success in many engineering applications. However, most existing image monitoring methods require fully observed images to implement modeling/monitoring. This requirement limits the application of these techniques for images… read more here.
