Timely detection of an event is one of the important tasks in many spatiotemporal applications. The unknown nature of the event makes the detection process challenging. Likelihood ratio (LR) methods have been widely used for identifying locations and change point times through searching the maximum evidence over temporal and spatial windows. However, the LR-based methods may not be optimal if shift...
The development of Statistical Process Control mostly focuses on temporal data. Those techniques are not sufficient for analyzing the manufacturing information embedded with spatial structure. The monitoring process that treats manufacturing records as purely multivariate data would miss important information of spatial relationship among the records. Thus, this paper proposes a spatial-EWMA test...
