Universal Adversarial Suffixes for Language Models Using Reinforcement Learning with Calibrated Reward

Sampriti Soor, Suklav Ghosh, Arijit Sur

Language models are vulnerable to short adversarial suffixes that can reliably alter predictions. Previous works usually find such suffixes with gradient search or rule-based metho…

Universal Adversarial Suffixes Using Calibrated Gumbel-Softmax Relaxation

Sampriti Soor, Suklav Ghosh, Arijit Sur

Language models (LMs) are often used as zero-shot or few-shot classifiers by scoring label words, but they remain fragile to adversarial prompts. Prior work typically optimizes tas…
