Learning Methods for Dynamic Topic Modeling in Automated Behaviour Analysis
Olga Isupova, Danil Kuzin, Lyudmila Mihaylova
Semi-supervised and unsupervised systems provide operators with invaluable support and can tremendously reduce the operators load. In the light of the necessity to process large vo…
Dynamic Hierarchical Dirichlet Process for Abnormal Behaviour Detection in Video
Olga Isupova, Danil Kuzin, Lyudmila Mihaylova
This paper proposes a novel dynamic Hierarchical Dirichlet Process topic model that considers the dependence between successive observations. Conventional posterior inference algor…
Anomaly detection in video with Bayesian nonparametrics
Olga Isupova, Danil Kuzin, Lyudmila Mihaylova
A novel dynamic Bayesian nonparametric topic model for anomaly detection in video is proposed in this paper. Batch and online Gibbs samplers are developed for inference. The paper…
