Explainable multi-class anomaly detection on functional data

2022-05-03 · Mathieu Cura, Katarina Firdova, Céline Labart, Arthur Martel

In this paper we describe an approach for anomaly detection and its explainability in multivariate functional data. The anomaly detection procedure consists of transforming the series into a vector of features and using an Isolation forest algorithm. The explainable procedure is based on the computation of the SHAP coefficients and on the use of a supervised decision tree. We apply it on simulated data to measure the performance of our method and on real data coming from industry.

Explainable Deep One-Class Classification

2020-07-03 · ICLR 2021 1 · Philipp Liznerski, Lukas Ruff, Robert A. Vandermeulen, Billy Joe Franks 외

Deep one-class classification variants for anomaly detection learn a mapping that concentrates nominal samples in feature space causing anomalies to be mapped away. Because this transformation is highly non-linear, findi…
