# MRAG-Bench: Vision-Centric Evaluation for Retrieval-Augmented Multimodal Models

[**🌐 Homepage**](https://mragbench.github.io/) | [**📖 Paper**](https://arxiv.org/abs/) | [**💻 Evaluation**](https://github.com/mragbench/MRAG-Bench) 


## Intro

MRAG-Bench consists of 16,130 images and 1,353 human-annotated multiple-choice questions across 9 distinct scenarios,  providing a robust and systematic evaluation of Large Vision Language Model (LVLM)’s vision-centric multimodal retrieval-augmented generation (RAG) abilities.

## Results

Evaluated upon 10 open-source and 4 proprietary LVLMs, our results show that all LVLMs exhibit greater improvements when augmented with images compared to textual knowledge. Notably, the top-performing model, GPT-4o, faces challenges in effectively leveraging retrieved knowledge, achieving only a 5.82% improvement with ground-truth information, in contrast to a 33.16% improvement observed in human participants. These findings highlight the importance of MRAG-Bench in encouraging the community to enhance LVLMs' ability to utilize retrieved visual knowledge more effectively.

## Load Dataset
The `data/` directory contains the full dataset annotations and images pre-loaded for processing with HF Datasets. It can be loaded as follows:

```python
from datasets import load_dataset
mrag_bench = load_dataset("uclanlp/MRAG-Bench")
```

| `image`| Contains image data in byte format |
| `gt_images`| A list of top 5 ground-truth images information |
| `question` | Question asked about the image |
| `A` | Choice A for the question |
| `B` | Choice B for the question |
| `C` | Choice C for the question |
| `D` | Choice D for the question |
|`answer_choice`|  Correct choice identifier |
| `answer` | Correct answer to the question |
| `image_type`| Type of image object |
| `source`| Source of the image |
| `retrieved_images`| A list of top 5 retrieved images information by CLIP |
