AnoShift (AnoShift: A Distribution Shift Benchmark for Unsupervised Anomaly Detection)

Introduced by Marius Dragoi et al. in AnoShift: A Distribution Shift Benchmark for Unsupervised Anomaly Detection30 Jun 2022 archive 2025-07-28

AnoShift is a large-scale anomaly detection benchmark, which focuses on splitting the test data based on its temporal distance to the training set, introducing three testing splits: IID, NEAR, and FAR. This testing scenario proves to capture the in-time performance degradation of anomaly detection methods for classical to masked language models.

AnoShift benchmark aims to enable a better estimate of the anomaly detection model’s performance, under natural distribution shifts that occur over time in the input, closer to the real-world performance, leading to more robust anomaly detection algorithms.

The benchmark is based on the Kyoto-2016 dataset (https://www.takakura.com/Kyoto_data/).

2 shown of 2 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 6. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
