# CMMMU
## Overview
CMMU (Chinese Massive Multi-discipline Multimodal Understanding) includes manually collected multimodal questions from college exams, quizzes, and textbooks, covering six core disciplines in Chinese. It is the Chinese counterpart to MMMU.
## Task Description
- **Task Type**: Chinese Multimodal Question Answering
- **Input**: Image(s) + question in Chinese with answer choices
- **Output**: Correct answer choice
- **Language**: Chinese
## Key Features
- 30 subjects across 6 core disciplines
- Art & Design, Business, Science, Health & Medicine, Humanities & Social Science, Tech & Engineering
- 39 heterogeneous image types (charts, diagrams, maps, tables, etc.)
- College-level difficulty
- Multiple question types (multiple-choice, true/false, short answer)
## Evaluation Notes
- Default configuration uses **0-shot** evaluation
- Evaluates on validation split
- Simple accuracy metric
- Chinese language prompts used
