The Perceptual Bandwidth Bottleneck in Vision-Language Models: Active Visual Reasoning via Sequential Experimental Design

Anjie Liu, Ziqin Gong, Yan Song +6

Visual perception in modern Vision-Language Models (VLMs) is constrained by a perceptual bandwidth bottleneck: a broad field of view preserves global context but sacrifices the fin…

A Survey of Process Reward Models: From Outcome Signals to Process Supervisions for Large Language Models

Congmin Zheng, Jiachen Zhu, Zhuoying Ou +8

Although Large Language Models (LLMs) exhibit advanced reasoning ability, conventional alignment remains largely dominated by outcome reward models (ORMs) that judge only final ans…
