# MathVision


## Overview

MATH-Vision (MATH-V) is a meticulously curated dataset of 3,040 high-quality mathematical problems with visual contexts sourced from real math competitions. It evaluates mathematical reasoning abilities in multimodal settings.

## Task Description

- **Task Type**: Visual Mathematical Reasoning
- **Input**: Math problem with visual context (diagram, figure, graph)
- **Output**: Numerical answer or answer choice
- **Domains**: Competition mathematics with visual elements

## Key Features

- Problems sourced from real mathematical competitions
- 3,040 high-quality problems with visual contexts
- Five difficulty levels (1-5) for granular analysis
- Supports both multiple-choice and free-form answers
- Includes detailed solutions for reference

## Evaluation Notes

- Default evaluation uses the **test** split
- Subsets by difficulty: `level 1` through `level 5`
- Primary metric: **Accuracy** with numeric comparison
- Free-form answers use \boxed{} format (without units)
- Multiple-choice uses CoT prompting with letter answers

{question}
Please reason step by step, and put your final answer within \boxed{{}} without units.
```

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets math_vision \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['math_vision'],
    dataset_args={
        'math_vision': {
            # subset_list: ['level 1', 'level 2', 'level 3']  # optional, evaluate specific subsets
        }
    },
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
