Explainable Outlier Detection Through Decision Tree Conditioning

v1.10.0-1 · Mar 5, 2026 · GPL (>= 3)

Description

Outlier detection method that flags suspicious values within observations, constrasting them against the normal values in a user-readable format, potentially describing conditions within the data that make a given outlier more rare. Full procedure is described in Cortes (2020) <doi:10.48550/arXiv.2001.00636>. Loosely based on the 'GritBot' <https://www.rulequest.com/gritbot-info.html> software.
