ASCD: Attention-Steerable Contrastive Decoding for Reducing Hallucination in MLLM

AAAI 2026technical

Multimodal large language models (MLLMs) frequently hallucinate by over-committing to spurious visual cues. Prior remedies–Visual and Instruction Contrastive Decoding (VCD, ICD)–mitigate this issue, yet the mechanism remains opaque. We first empirically show that their improvements systematically co
