Healthcare GPT-2 LoRA Model

A fine-tuned GPT-2 model specialized for healthcare and medical text generation using LoRA (Low-Rank Adaptation).

Model Details

• Model Name: healthcare-gpt2-lora
• Base Model: gpt2
• Model Type: LoRA Adapter (PEFT)
• Fine-tuning Method: LoRA (Low-Rank Adaptation)
• Language: English
• Domain: Healthcare, Medical

Model Description

This model is a fine-tuned version of GPT-2, optimized for healthcare-related text generation. It has been trained on healthcare datasets including clinical notes, medical Q&A, medication information, and other medical text data.

The model uses LoRA (Low-Rank Adaptation) for efficient fine-tuning, allowing it to be trained with minimal computational resources while maintaining the base model's general language capabilities.

Uses

Direct Use

This model is intended for:

• Generating healthcare-related text
• Medical documentation assistance
• Clinical note generation
• Medical Q&A systems
• Healthcare chatbot applications

Example Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained("gpt2")
tokenizer = AutoTokenizer.from_pretrained("gpt2")

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "./cpu_healthcare_output")

# Generate text
prompt = "Patient presents with:"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=200, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training Details

Training Data

The model was fine-tuned on healthcare datasets including:

• Clinical notes
• Medical Q&A pairs
• Medication information
• Lab results and vital signs
• Medical history records

Training Hyperparameters

• LoRA Rank (r): 8
• LoRA Alpha: 16
• LoRA Dropout: 0.1
• Learning Rate: 5e-5
• Batch Size: 1
• Max Length: 128-256 tokens

Limitations

• This is a small model (GPT-2 base) optimized for CPU training
• For better performance, consider using larger models like Mistral-7B with GPU
• The model should not be used for actual medical diagnosis or treatment decisions
• Always verify medical information with qualified healthcare professionals

Recommendations

• Use this model as an assistant tool, not as a replacement for medical professionals
• Verify all generated medical information
• Consider fine-tuning on domain-specific datasets for specialized use cases
• For production use, consider using larger models trained on more extensive datasets
