Libraries

How to use RobinY99/MR-IQA with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="RobinY99/MR-IQA")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("RobinY99/MR-IQA")
model = AutoModelForMultimodalLM.from_pretrained("RobinY99/MR-IQA")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

MR-IQA: A Unified Margin View of Regression and Ranking for Blind Image Quality Assessment

arXiv | GitHub

We derive that regression and ranking are approximately equivalent under a unified margin view. Based on this observation, we propose MR-IQA for margin learning in blind image quality assessment.

Validation Snapshot

The released checkpoint was validated after each epoch with an 8-shard setup on a held-out KONIQ split.

Epoch	Valid samples	SRCC	PLCC	Shards
1	200	0.8840	0.8894	8
2	200	0.9213	0.9302	8
3	200	0.9318	0.9392	8
4	200	0.9274	0.9340	8
5	200	0.9271	0.9409	8
6	200	0.9249	0.9406	8
7	200	0.9205	0.9408	8
8	200	0.9288	0.9465	8
9	200	0.9307	0.9450	8
10	200	0.9251	0.9421	8

Best SRCC was reached at epoch 3. The final released checkpoint corresponds to epoch 10. Sanitized training metadata is available in training_guidance/.

Quick Start

Load the model with a standard Transformers vision-language workflow. The training and evaluation code use a no-reasoning prompt and parse the final numeric score from <answer>...</answer>.

System prompt:

You are an image quality assessment assistant. Output only the final score in <answer> </answer> tags.

User prompt:

What is your overall rating on the quality of this picture? The rating should be a float between 1 and 5, rounded to two decimal places, with 1 representing very poor quality and 5 representing excellent quality. Please only output the final answer with one score in <answer> </answer> tags.

Output Format

The expected response is only one score in answer tags:

<answer>3.74</answer>

The evaluation parser first reads the number inside <answer>...</answer> and clamps valid scores to the 1 to 5 range.
