PromptCD: Test-Time Behavior Enhancement via Polarity-Prompt Contrastive Decoding
Abstract: We present PromptCD, a test-time method for controlling LLM behavior without additional training. The approach creates paired positive and negative guiding prompts for a target behavior and contrasts model responses at the token-probability level for LLMs and through visual attention patterns for VLMs.
