# CardioEmbed-Jina-v2

**Domain-specialized cardiology text embeddings using LoRA-adapted Jina-v2**

Part of a comparative study of 10 embedding architectures for clinical cardiology.

## Performance

| Metric | Score |
|--------|-------|
| Separation Score | **-0.175** |

## Usage

```python
from transformers import AutoModel, AutoTokenizer
from peft import PeftModel

base_model = AutoModel.from_pretrained("jinaai/jina-embeddings-v2-base-en")
tokenizer = AutoTokenizer.from_pretrained("jinaai/jina-embeddings-v2-base-en")
model = PeftModel.from_pretrained(base_model, "richardyoung/CardioEmbed-Jina-v2")
```

## Training

- **Training Data**: 106,535 cardiology text pairs from medical textbooks
- **Method**: LoRA fine-tuning (r=16, alpha=32)
- **Loss**: Multiple Negatives Ranking Loss (InfoNCE)
