Hierarchical Process Reward Models are Symbolic Vision Learners

CVPR 2026

Symbolic computer vision represents diagrams through explicit logical rules and structured representations, enabling interpretable understanding in machine vision. This requires fundamentally different learning paradigms from pixel-based visual models. Symbolic visual learners parse diagrams into ge

Math Blind: Failures in Diagram Understanding Undermine Reasoning in MLLMs

ICLR 2026poster

Diagrams represent a form of visual language that encodes abstract concepts and relationships through structured symbols and their spatial arrangements. Unlike natural images, they are inherently symbolic, and entirely artificial. They thus pose unique challenges for Multimodal Large Language Model…

Primitive Vision: Improving Diagram Understanding in MLLMs

ICML 2025poster

Mathematical diagrams have a distinctive structure. Standard feature transforms designed for natural images (e.g., CLIP) fail to process them effectively, limiting their utility in multimodal large language models (MLLMs). Current efforts to improve MLLMs have primarily focused on scaling mathematic…
