Opportunistic Target Selection: Early Directional Commitment for Query-Efficient Black-Box Adversarial Attacks 事件

Opportunistic Target Selection: Early Directional Commitment for Query-Efficient Black-Box Adversarial Attacks arXiv:2605.25663v1 Announce Type: cross Abstract: Black-box adversarial attacks that minimize only the ground-truth confidence suffer from class drift: perturbations wander through the feature space without committing to a specific adversarial class, wasting queries on diffuse, undirected progress. We introduce Opportunistic Target Selection (OTS), a lightweight wrapper that switches a
