✓ Portable graph bundle live · download bundle · merged state

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

VGPO achieves better visual activation and superior performance in mathematical multimodal reasoning and visual-dependent tasks through Visual Attention Compensation and dual-grained advantage re-weighting.

C2weakest assumption

That amplifying visual cues via similarity metrics and re-weighting advantages based on visual activation will reliably counteract forgetting without destabilizing the policy or degrading text-based reasoning performance.

C3one line summary

VGPO introduces visual attention compensation and dual-grained advantage re-weighting to reinforce visual focus in VLMs, yielding better activation and performance on multimodal reasoning tasks.
