Revisiting the Platonic Representation Hypothesis: An Aristotelian View

Fabian Gröger, Shuo Wen, Maria Brbić

The Platonic Representation Hypothesis suggests that representations from neural networks are converging to a common statistical model of reality. We show that the existing metrics…

Representation-Based Data Quality Audits for Audio

Alvaro Gonzalez-Jimenez, Fabian Gröger, Linda Wermelinger +4

Data quality issues such as off-topic samples, near duplicates, and label errors often limit the performance of audio-based systems. This paper addresses these issues by adapting S…

Clinical Uncertainty Impacts Machine Learning Evaluations

Simone Lionetti, Fabian Gröger, Philippe Gottfrois +4

Clinical dataset labels are rarely certain as annotators disagree and confidence is not uniform across cases. Typical aggregation procedures, such as majority voting, obscure this…
