miRNA-BioBERT is a fine-tuned version of BioBERT, trained specifically for classifying sentences as miRNA-related (relevant) or not (irrelevant). The model is useful for automating literature reviews, extracting relevant sentences, and identifying key insights in genomic research.

✔ Base Model: dmis-lab/biobert-base-cased-v1.1
✔ Fine-tuning Method: LoRA (Low-Rank Adaptation)
✔ Dataset: Curated biomedical text corpus containing labeled miRNA-relevant and non-relevant sentences
✔ Task: Binary classification (1 = functional, 0 = non-functional)
✔ Trained on: RTX A6000 GPU (5 epochs, batch size 32, learning rate 2e-5)

🚀 How to Use the Model

1️⃣ Install Dependencies

pip install transformers torch

python

from transformers import AutoModelForSequenceClassification, AutoTokenizer  
import torch  

# Load the model and tokenizer  
model_name = "debjit20504/miRNA-biobert"  
tokenizer = AutoTokenizer.from_pretrained(model_name)  
model = AutoModelForSequenceClassification.from_pretrained(model_name)  

# Move model to GPU or MPS (for Mac)  
device = torch.device("mps") if torch.backends.mps.is_available() else torch.device("cuda" if torch.cuda.is_available() else "cpu")  
model.to(device)  
model.eval()

def classify_text(text):  
    inputs = tokenizer(text, return_tensors="pt").to(device)  
    with torch.no_grad():  
        output = model(**inputs)  
        label = torch.argmax(output.logits, dim=1).item()  
    return "functional" if label == 1 else "Non-functional"  

# Example Test  
sample_text = "The results showed that miR-223-3p decreased in glioblastoma tissue but NLRP3 increased."  
print(f"Classification: {classify_text(sample_text)}")
