Attacking Motion Planners Using Adversarial Perception Errors

no code implementations21 Nov 2023 Jonathan Sadeghi, Nicholas A. Lord, John Redford, Romain Mueller

Autonomous driving (AD) systems are often built and tested in a modular fashion, where the performance of different modules is measured using task-specific metrics.

An Active Learning Reliability Method for Systems with Partially Defined Performance Functions

1 code implementation5 Oct 2022 Jonathan Sadeghi, Romain Mueller, John Redford

This enables active learning Gaussian process methods to be applied to problems where the performance of the system is sometimes undefined, and we demonstrate the effectiveness of our approach by testing our methodology on synthetic numerical examples for the autonomous driving domain.

Query-based Hard-Image Retrieval for Object Detection at Test Time

1 code implementation23 Sep 2022 Edward Ayers, Jonathan Sadeghi, John Redford, Romain Mueller, Puneet K. Dokania

There is a longstanding interest in capturing the error behaviour of object detectors by finding images where their performance is likely to be unsatisfactory.

Autonomous Driving Image Retrieval +2

A Step Towards Efficient Evaluation of Complex Perception Tasks in Simulation

no code implementations28 Sep 2021 Jonathan Sadeghi, Blaine Rogers, James Gunn, Thomas Saunders, Sina Samangooei, Puneet Kumar Dokania, John Redford

There has been increasing interest in characterising the error behaviour of systems which contain deep learning models before deploying them into any safety-critical scenario.
