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…
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…
Online Non-Stationary Stochastic Quasar-Convex Optimization
Yuen-Man Pun, Iman Shames
Recent research has shown that quasar-convexity can be found in applications such as identification of linear dynamical systems and generalized linear models. Such observations hav…
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…
