Usage

from transformers import AutoModel, AutoTokenizer
from peft import PeftModel

base_model = AutoModel.from_pretrained("google/gemma-2-2b-it")
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-2b-it")
model = PeftModel.from_pretrained(base_model, "richardyoung/CardioEmbed-Gemma-2-2B")

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)
