World-Calibrated Proposal-to-Action Flow for Vision-Language-Action Models
World-Calibrated Proposal-to-Action Flow for Vision-Language-Action Models
ProAct is a world-calibrated proposal-to-action framework for Vision-Language-Action (VLA) models that enhances motion continuity and scene prediction. It introduces a lightweight Proposal Expert and a prospective World Expert to jointly capture intended scene evolution and proposal-future compatibility, leading to improved performance and reduced inference latency.
