Abstract:
|
This paper introduces a mixture modeling approach appropriate for a large monitoring network in which measurements and associated covariates are taken over time. The proposed approach is developed for unveiling the clustering structure of data, which can help the prediction accuracy as well as understanding of physical system. The modeling framework can incorporate a complex structure of the data with an efficient algorithm for real-time model fitting. We also provide a criterion for selection of the optimal number of clusters. Our approach is illustrated using simulation studies and a solar energy forecasting problem.
