Adversarial patches to Vision-Language-Action (VLA) policies can cause both immediate action corruption and persistent state effects that remain after the patch is removed. Existin…
Runtime Safety Filtering for Two-Terminal Hazards in Robotic Battery Recycling
Yuxin Cao, Wei Song, Xianglin Yang +4
Runtime safety filters for learned manipulation policies typically define unsafe states as unions of object-wise keep-out regions. This representation can be unnecessarily restrict…
KeyBound: Keyed and Host-Bound Learned Audio Watermarking for Speech Provenance
Bangshuo Zhu, Yuxin Cao, Weifei Jin +4
Audio watermarking is a proactive route to attributing synthetic speech to its source. Learned audio watermarks are typically judged by payload recovery after a fixed catalog of si…
