Minimisation of Quasar-Convex Functions Using Random Zeroth-Order Oracles
Amir Ali Farzin, Yuen-Man Pun, Philipp Braun +1
This paper explores the performance of a random Gaussian smoothing zeroth-order (ZO) scheme for minimising quasar-convex (QC) and strongly quasar-convex (SQC) functions in both unc…

Adversarial Attacks and Detection in Visual Place Recognition for Safer Robot Navigation
Connor Malone, Owen Claxton, Iman Shames +1
Stand-alone Visual Place Recognition (VPR) systems have little defence against a well-designed adversarial attack, which can lead to disastrous consequences when deployed for robot…

Improving Visual Place Recognition Based Robot Navigation By Verifying Localization Estimates
Owen Claxton, Connor Malone, Helen Carson +4
Visual Place Recognition (VPR) systems often have imperfect performance, affecting the `integrity' of position estimates and subsequent robot navigation decisions. Previously, SVM…
