CardioEmbed-Qwen2.5-0.5B

Domain-specialized cardiology text embeddings using LoRA-adapted Qwen2.5-0.5B

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

Performance

Usage

from transformers import AutoModel, AutoTokenizer
from peft import PeftModel

base_model = AutoModel.from_pretrained("Qwen/Qwen2.5-0.5B")
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-0.5B")
model = PeftModel.from_pretrained(base_model, "richardyoung/CardioEmbed-Qwen2.5-0.5B")

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)
