TL;DR

This work presents the first online outlier exploration platform, called ONION, that enables analysts to effectively explore anomalies even in large datasets and confirms the effectiveness of ONION in recognizing "true" outliers.

Abstract

Traditional outlier detection systems process each individual outlier detection request instantiated with a particular parameter setting one at a time. This is not only prohibitively time-consuming for large datasets, but also tedious for analysts as they explore the data to hone in on the appropriate parameter setting and desired results.
