Overlooked Data in Typological Databases: What Grambank Teaches Us About Gaps in Grammars

no code implementations LREC 2022 Jakob Lesage, Hannah J. Haynie, Hedvig Skirgård, Tobias Weber, Alena Witzlack-Makarevich

We then aggregate these comments and the coded values to derive a level of description for 17 grammatical domains that Grambank covers (negation, adnominal modification, participant marking, tense, aspect, etc.).

Unreading Race: Purging Protected Features from Chest X-ray Embeddings

no code implementations2 Nov 2023 Tobias Weber, Michael Ingrisch, Bernd Bischl, David Rügamer

Materials and Methods: An orthogonalization is utilized to remove the influence of protected features (e. g., age, sex, race) in chest radiograph embeddings, ensuring feature-independent results.

Adversarial Anomaly Detection using Gaussian Priors and Nonlinear Anomaly Scores

1 code implementation27 Oct 2023 Fiete Lüer, Tobias Weber, Maxim Dolgich, Christian Böhm

Anomaly detection in imbalanced datasets is a frequent and crucial problem, especially in the medical domain where retrieving and labeling irregularities is often expensive.
