I was wondering, has anyone here applied cluster analysis techniques for anomaly detection?
I read a paper that used it for insurance fraud detection, but I don't know what other fields are using clustering to detect frauds and abnormalities?
I'd be grateful if someone can help.
- gesman 8y agoYes, tons of that. See this - using K-Means clustering for anomaly detection in web traffic: https://imgur.com/a/qWMgUo0 https://imgur.com/a/qWMgUo0 Using DBscan clustering for anomaly detection in healthcare claims data (detecting doctors who anomalously prescribing opioids). Using public CMS data set from 2015. 4 out of 8 top anomalies (doctors) were later actually convicted of crimes or gone into all sort of troubles with DOJ: https://imgur.com/a/6wFWTg5 https://imgur.com/a/6wFWTg5 https://imgur.com/a/f721ndb https://imgur.com/a/f721ndb (Splunk Enterprise + free apps was used to ingest data and build all this logic and dashboards)
