SVSR: A Self-Verification and Self-Rectification Paradigm for Multimodal Reasoning

Fei Luo, Hebei Li, Nianbing Su, Yanbiao Ma, Yueying Li, Zhe Qian, Zhonghua Wang, Zhongxing Xu, Zhuohan Ouyang

Multimodal models learn to verify and correct their own reasoning steps through a three-stage training process.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

SVSR improves reasoning accuracy and enables stronger generalization to unseen tasks and question types. Notably, once trained with explicit self-reflective reasoning, the model also exhibits improved implicit reasoning ability, outperforming strong baselines even when no explicit reasoning traces are provided.

C2weakest assumption

That refining reasoning traces from pre-trained VLMs and filtering model-generated traces with a teacher VLM produces data that genuinely teaches robust self-verification rather than just memorizing patterns or teacher biases.

C3one line summary

SVSR trains multimodal models to verify and correct their own reasoning using a preference dataset, supervised fine-tuning, and semi-online DPO with a teacher model.
