Trust Me, I Know the Way: Predictive Uncertainty in the Presence of Shortcut Learning

Lisa Wimmer, Bernd Bischl, Ludwig Bothmann

The correct way to quantify predictive uncertainty in neural networks remains a topic of active discussion. In particular, it is unclear whether the state-of-the art entropy decomp…

Privilege Scores

Ludwig Bothmann, Philip A. Boustani, Jose M. Alvarez +3

Bias-transforming methods of fairness-aware machine learning aim to correct a non-neutral status quo with respect to a protected attribute (PA). Current methods, however, lack an e…

Overcoming Fairness Trade-offs via Pre-processing: A Causal Perspective

Charlotte Leininger, Simon Rittel, Ludwig Bothmann

Training machine learning models for fair decisions faces two key challenges: The \emph{fairness-accuracy trade-off} results from enforcing fairness which weakens its predictive pe…

What Is Fairness? On the Role of Protected Attributes and Fictitious Worlds

Ludwig Bothmann, Kristina Peters, Bernd Bischl

A growing body of literature in fairness-aware machine learning (fairML) aims to mitigate machine learning (ML)-related unfairness in automated decision-making (ADM) by defining me…
