Abstract

To accelerate simultaneous execution of multiple change point detection (CPD) queries, this paper proposes to apply the multiple query optimization scheme which has been studied in DBMS or DSMS. We propose to share a part of steps of CPD procedures, and we propose an algorithm for the sharing. The result of experiments showed that our proposal reduces more than 80 % internal steps and achieved 5 times performance improvement. To the best of our knowledge, this is the first work that applies the multiple query optimization scheme for CPD.
