Because the Closed Frequent Patterns (CFPs) are the subsets of FPs and its scale is much less, thus, CFP-based Anomaly Detection (AD) methods are more efficient in time. However, the small scale of patterns used in the AD process led to low detection efficiency. That is, the time efficiency and detection accuracy of FP-based anomaly detection are two contradictory individuals. Aimed at this problem, this paper introduces an AD method based on the distance of CFPs, namely Anomaly Detection Based on the Distance of Closed Frequent Patterns (AD-DCFP). AD-DCFP uses the distance of CFPs (the discrepancy between CFPs and data samples) to eliminate the negative impact of patterns with small scale used in the AD, thereby quickly and accurately detecting anomalies. Specifically, the vertical-based mining manner and bit-vector structure are used to mine CFPs for improving mining efficiency; And then, the concept of pattern distance is introduced in the AD phase to calculate the abnormal degree of each data sample; Finally, the data samples with top-k ranked abnormal degree are judged as anomalies. Massive experiments on six datasets show that compared with five state-of-the-arts, the proposed AD-DCFP method can improve the average detection accuracy by about 5% and reduce the time consumption by about 10%, it is a better choice for large-scale or high-dimensional datasets<\/jats:p>","DOI":"10.34028\/iajit\/22\/2\/6","type":"journal-article","created":{"date-parts":[[2025,2,18]],"date-time":"2025-02-18T07:57:55Z","timestamp":1739865475000},"source":"Crossref","is-referenced-by-count":0,"title":["AD-DCFP: Anomaly Detection Based on the Distance of Closed Frequent Patterns"],"prefix":"10.34028","volume":"22","author":[{"given":"Yudong","family":"Yin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linqiang","family":"Deng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"19944","published-online":{"date-parts":[[2025]]},"container-title":["The International Arab Journal of Information Technology"],"original-title":[],"language":"en","deposited":{"date-parts":[[2025,3,9]],"date-time":"2025-03-09T07:39:40Z","timestamp":1741505980000},"score":1,"resource":{"primary":{"URL":"https:\/\/iajit.org\/upload\/files\/AD-DCFP-Anomaly-Detection-Based-on-the-Distance-of-Closed-Frequent-Patterns.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2025]]},"published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.34028\/iajit\/22\/2\/6","archive":["Internet Archive"],"relation":{},"ISSN":["2309-4524","1683-3198"],"issn-type":[{"type":"electronic","value":"2309-4524"},{"type":"print","value":"1683-3198"}],"subject":[],"published":{"date-parts":[[2025]]}}}
