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