Abstract
In this chapter, we provide an overview of the recent development of the online change detection approach for data sequence based on martingale computed using p-values derived from nonconformity scores for observed data. In particular, we summarize and discuss (1) the effectiveness of the change detection method on different scenarios and (2) implementation issues related to the martingale-based change detection method.
