## Model Description

This model is a CLIP-style vision–language model trained on 20% of BIOMEDICA dataset using CLIPScore.


**Technical Specifications:**
* **Base model:** `facebook/metaclip-b16-400m` (CLIP-like architecture)
* **Architecture:** `CLIPModel` from the `transformers` library
* **Processor:** `CLIPProcessor` (handles both image and text preprocessing)

**Example Usage**
```python
from transformers import CLIPProcessor, CLIPModel
from PIL import Image
import requests
import torch

model_id = "Mihara-bot/metaclip-b16-400m-biomedica_CLIPScore_20"  

processor = CLIPProcessor.from_pretrained(model_id)
model = CLIPModel.from_pretrained(model_id)

# Example image & text
url = "https://your-image-url"
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
texts = ["a medical image of ...", "a normal image of ..."]

inputs = processor(
    text=texts,
    images=image,
    return_tensors="pt",
    padding="max_length",
    truncation=True,
    max_length=77,
)

with torch.no_grad():
    outputs = model(
        pixel_values=inputs["pixel_values"],
        input_ids=inputs["input_ids"],
        attention_mask=inputs["attention_mask"],
    )

image_embeds = outputs.image_embeds      # (batch, dim)
text_embeds = outputs.text_embeds        # (batch, dim)

# Calculate similarity
logits_per_image = image_embeds @ text_embeds.t()
probs = logits_per_image.softmax(dim=-1)
print(probs)
```


**Intended Use**

- Vision–language tasks such as image–text retrieval, zero-shot classification, or image–text similarity in the biomedical/medical domain 
(depending on the specific dataset subset used).

- Research on data selection, influence functions, and the efficient adaptation of CLIP models.

**Not Intended For**

Any safety‑critical clinical diagnosis or automated medical decision-making.

Any deployment without human oversight, especially within healthcare environments.

**Limitations**

The model is trained on selected subsets of the BIOMEDICA dataset; it may reflect the biases and coverage limitations of the underlying dataset.

Performance outside the target domain (e.g., general web images) is likely weaker than generic CLIP models.

Training text largely consists of short captions; performance on long, structured clinical narratives may be limited.
