Seeing Clearly, Answering Incorrectly: A Multimodal Robustness Benchmark for Evaluating MLLMs on Leading Questions

📖 Paper | 🏠 Code | 📖 Data

Overview

MMR provides a comprehensive suite to evaluate the understanding capabilities of Multimodal Large Language Models (MLLMs) and their robustness when handling negative questions after correctly interpreting visual content. The MMR benchmark includes:

1. Multimodal Robustness (MMR) Benchmark and Targeted Evaluation Metrics:

   • Comprising 12 categories of paired positive and negative questions.
   • Each question is meticulously annotated by experts to ensure scientific validity and accuracy.

2. Specially Designed Training Set:

   • Contains paired positive and negative visual question-answer samples to enhance robustness.

3. Combined Dataset and Models:

   • The new dataset merges the proposed dataset with existing ones.
   • Trained models include Bunny-MMR-3B, Bunny-MMR-4B, and Bunny-MMR-8B.

In this repository, we provide Bunny-MMR-8B, which is built upon SigLIP and Llama-3-8B-Instruct. More details about this model can be found in GitHub.

Key Features

• Rigorous Testing:

  • Extensive testing on leading MLLMs shows that while these models can correctly interpret visual content, they exhibit significant vulnerabilities when faced with leading questions.

• Enhanced Robustness:

  • The targeted training significantly improves the MLLMs' ability to handle negative questions effectively.

Quickstart

Here we show a code snippet to show you how to use the model with transformers.

Before running the snippet, you need to install the following dependencies:

pip install torch transformers accelerate pillow

import torch
import transformers
from transformers import AutoModelForCausalLM, AutoTokenizer
from PIL import Image
import warnings

# disable some warnings
transformers.logging.set_verbosity_error()
transformers.logging.disable_progress_bar()
warnings.filterwarnings('ignore')

# set device
torch.set_default_device('cpu')  # or 'cuda'

# create model
model = AutoModelForCausalLM.from_pretrained(
    'AI4VR/Bunny-MMR-8B',
    torch_dtype=torch.float16,
    device_map='auto',
    trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained(
    'AI4VR/Bunny-MMR-8B',
    trust_remote_code=True)

# text prompt
prompt = 'text prompt'
text = f"A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER: <image>\n{prompt} ASSISTANT:"
text_chunks = [tokenizer(chunk).input_ids for chunk in text.split('<image>')]
input_ids = torch.tensor(text_chunks[0] + [-200] + text_chunks[1][1:], dtype=torch.long).unsqueeze(0)

# image, sample images can be found in images folder
image = Image.open('path/to/image')
image_tensor = model.process_images([image], model.config).to(dtype=model.dtype)

# generate
output_ids = model.generate(
    input_ids,
    images=image_tensor,
    max_new_tokens=100,
    use_cache=True)[0]

print(tokenizer.decode(output_ids[input_ids.shape[1]:], skip_special_tokens=True).strip())
