The cluster-based model is proposed, which is constructed on conditionally independent Gaussian clusters captured in real time using recursive algorithms of the Bayesian mixture estimation theory. The resulting model is expected to be used for predicting count data using real time Gaussian observations. The Poisson distribution of the count data is used as a basic model. However, in reality, count data often do not satisfy the Poisson assumption of equal mean and variance. For this case, five cluster-based Poisson-related models of overdispersed data have been studied. The experimental part of the chapter demonstrates a comparison of the prediction accuracy of the considered models with two theoretical counterparts for the case of weak and strong overdispersion with the help of simulations. The paper reports that the most accurate prediction in average has been provided by the cluster-based Generalized Poisson models. cav_un_auth*0446747 ICINCO 2021 : International Conference on Informatics in Control, Automation and Robotics /18./ 20210706 20210708 online CH BB 10000 10100 10103 2024 2 PR RVO:67985556 https://hdl.handle.net/11104/0340877 S 49 0.148 16.03 0.31 4693 Q4 2023 M SCOPUS PUBMED WOS pdf cav_un_epca*0569489 Informatics in Control, Automation and Robotics.
