Most of the anomaly detection algorithms require setting of some parameters which significantly affect the performance of the algorithm. These parameters are generally set by hit-and-trial; hence performance is compromised with default or random values. In this paper, the authors propose a self-optimizing algorithm for anomaly detection based on firefly meta-heuristic, and named as Firefly Algorithm for Anomaly Detection (FAAD). The proposed solution is a non-clustering unsupervised learning approach for anomaly detection. The algorithm is implemented on Apache Spark for scalability and hence the solution can handle big data as well. Experiments were conducted on various datasets, and the results show that the proposed solution is much accurate than the standard algorithms of anomaly detection.<\/jats:p>","DOI":"10.34028\/iajit\/17\/2\/16","type":"journal-article","created":{"date-parts":[[2020,2,18]],"date-time":"2020-02-18T09:00:06Z","timestamp":1582016406000},"page":"272-280","source":"Crossref","is-referenced-by-count":2,"title":["FAAD: A Self-Optimizing Algorithm for Anomaly Detection"],"prefix":"10.34028","volume":"17","author":[{"given":"Adeel","family":"Hashmi","sequence":"first","affiliation":[{"name":"Department of Computer Engineering, Jamia Millia Islamia, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanvir","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Jamia Millia Islamia, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"19944","published-online":{"date-parts":[[2019,2,28]]},"container-title":["The International Arab Journal of Information Technology"],"original-title":[],"language":"en","deposited":{"date-parts":[[2020,2,18]],"date-time":"2020-02-18T09:00:19Z","timestamp":1582016419000},"score":1,"resource":{"primary":{"URL":"https:\/\/iajit.org\/PDF\/Vol%2017,%20No.%202\/16909.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,2,28]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,2,28]]},"published-print":{"date-parts":[[2020,2,28]]}},"URL":"https:\/\/doi.org\/10.34028\/iajit\/17\/2\/16","archive":["Internet Archive","Internet Archive"],"relation":{},"ISSN":["2309-4524","1683-3198"],"issn-type":[{"value":"2309-4524","type":"electronic"},{"value":"1683-3198","type":"print"}],"subject":[],"published":{"date-parts":[[2019,2,28]]}}}
