Stylist: Style-Driven Feature Ranking for Robust Novelty Detection

1 code implementation5 Oct 2023 Stefan Smeu, Elena Burceanu, Emanuela Haller, Andrei Liviu Nicolicioiu

Similar to works in out-of-distribution generalization, we propose to use the formalization of separating into semantic or content changes, that are relevant to our task, and style changes, that are irrelevant.

Environment-biased Feature Ranking for Novelty Detection Robustness

no code implementations21 Sep 2023 Stefan Smeu, Elena Burceanu, Emanuela Haller, Andrei Liviu Nicolicioiu

Thus, we propose a method that starts with a pretrained embedding and a multi-env setup and manages to rank the features based on their environment-focus.

Env-Aware Anomaly Detection: Ignore Style Changes, Stay True to Content!

no code implementations6 Oct 2022 Stefan Smeu, Elena Burceanu, Andrei Liviu Nicolicioiu, Emanuela Haller

We introduce a formalization and benchmark for the unsupervised anomaly detection task in the distribution-shift scenario.
