Chain-of-Thought Compression Should Not Be Blind: V-Skip for Efficient Multimodal Reasoning via Dual-Path Anchoring (2026.acl-long)
Copied to clipboard
| Challenge: | Existing efforts to mitigate this via token compression fail due to its autoregressive nature . linguistically redundant tokens are erroneously pruned, leading to hallucinations . |
| Approach: | They propose a method that reformulates token pruning as a Visual-Anchored Information Bottleneck (VA-IB) optimization problem. |
| Outcome: | Experiments on Qwen2-VL and Llama-3.2 families show that the proposed model achieves a speedup with negligible accuracy loss. |
