PIVOT: Dual-Level Learning Framework Anchoring Visually-Grounded Multimodal Reasoning
arXiv:2609.18057v1 proposes PIVOT, a dual-level learning framework for LVLMs that adds a self-calibrated experience replay to retain informative visually-grounded trajectories and a vision-guided advantage allocation to boost tokens with strong local visual support; experiments report competitive gains on diverse multimodal reasoning benchmarks.
