Researchers propose new uncertainty elicitation techniques for large language models using imprecise probabilities framework to better capture higher-order uncertainty. The approach addresses systematic failures in ambiguous question-answering and self-reflection by quantifying both first-order uncertainty over responses and second-order uncertainty about the probability model itself.
Researchers have developed PV-VASM, a probabilistic framework for verifying the robustness of voice anti-spoofing models against deepfake attacks. The model-agnostic approach estimates misclassification probability under various speech synthesis techniques including text-to-speech and voice cloning, providing formal robustness guarantees against unseen generation methods.
Researchers propose a new concept-based adversarial attack framework that targets entire concept distributions rather than single images, generating diverse adversarial examples while preserving the original concept identity. The method creates adversarial images with variations in pose, viewpoint, or background that can still mislead classifiers while remaining recognizable as instances of the original category.
