Abstract
We propose an extension of Support Vector Machines (SVMs) regression for spatio-temporal data mining. As a case study, we apply our method
for deriving an automated controller for the North Platte River reservoir system. The North Platte River reservoir system has multiple
reservoirs, whose spatial locations and temporal variables have been incorporated in data mining. The resultant controller operates such
that at each reservoir its status changes over time by the opening and closing of a dam to control its water levels. We further increased
the efficiency of the controller by inputting the spatio-temporal features that were deduced by Principal Component Analysis (PCA). Our
experiments show that the SVM with regression method combined with PCA can be a basis of an efficient and accurate spatio-temporal data
mining method.
