Systematic construction of anomaly detection benchmarks from real data
TL;DR: In this paper, the authors introduce a methodology for transforming existing classification data sets into ground-truthed benchmark data sets for anomaly detection, which produces data sets that vary along three important dimensions: (a) point difficulty, (b) relative frequency of anomalies, and (c) clusteredness.
Proceedings ArticleDOI
Incorporating Expert Feedback into Active Anomaly Discovery
TL;DR: This paper describes an Active Anomaly Discovery method for incorporating expert feedback to adjust the anomaly detector so that the outliers it discovers are more in tune with the expert user's semantic understanding of the anomalies.

A Meta-Analysis of the Anomaly Detection Problem
TL;DR: A thorough meta-analysis of the anomaly detection problem is provided, providing an ontology for describing anomaly detection contexts, a methodology for controlling various aspects of benchmark creation, guidelines for future experimental design and a discussion of the many potential pitfalls of trying to measure success in this field.
