Towards Understanding The Semidefinite Relaxations of Truncated Least-Squares in Robust Rotation Search

2022 · arXiv (Cornell University)

The rotation search problem aims to find a 3D rotation that best aligns a given number of point pairs. To induce robustness against outliers for rotation search, prior work considers truncated least-squares (TLS), which is …

Disentangling Safe and Unsafe Corruptions via Anisotropy and Locality

2025 · arXiv (Cornell University)

State-of-the-art machine learning systems are vulnerable to small perturbations to their input, where ``small'' is defined according to a threat model that assigns a positive threat to each perturbation. Most prior works define a task-agnostic, …

KDA: A Knowledge-Distilled Attacker for Generating Diverse Prompts to Jailbreak LLMs

2025 · arXiv (Cornell University)

Jailbreak attacks exploit specific prompts to bypass LLM safeguards, causing the LLM to generate harmful, inappropriate, and misaligned content. Current jailbreaking methods rely heavily on carefully designed system prompts and numerous queries to achieve a …
