Adaptive Bounding Box Uncertainties via Two-Step Conformal Prediction

no code implementations12 Mar 2024 Alexander Timans, Christoph-Nikolas Straehle, Kaspar Sakmann, Eric Nalisnick

In particular, we leverage conformal prediction to obtain uncertainty intervals with guaranteed coverage for object bounding boxes.

Autonomous Driving Conformal Prediction +3

A powerful rank-based correction to multiple testing under positive dependency

no code implementations17 Nov 2023 Alexander Timans, Christoph-Nikolas Straehle, Kaspar Sakmann, Eric Nalisnick

We develop a novel multiple hypothesis testing correction with family-wise error rate (FWER) control that efficiently exploits positive dependencies between potentially correlated statistical hypothesis tests.

Uncertainty Quantification for Image-based Traffic Prediction across Cities

1 code implementation11 Aug 2023 Alexander Timans, Nina Wiedemann, Nishant Kumar, Ye Hong, Martin Raubal

We compare two epistemic and two aleatoric UQ methods on both temporal and spatio-temporal transfer tasks, and find that meaningful uncertainty estimates can be recovered.
