My LLM Model: Dementia Knowledge Assistant

Model Name: Dementia-llm-model
Description:
This is a fine-tuned Large Language Model (LLM) designed to assist with dementia-related knowledge retrieval and question-answering tasks. The model uses advanced embeddings (hkunlp/instructor-large) and a FAISS vector store for efficient contextual search and retrieval.

Model Summary

This LLM is fine-tuned on a dataset specifically curated for dementia-related content, including medical knowledge, patient care, and treatment practices. It leverages state-of-the-art embeddings to generate accurate and contextually relevant answers to user queries. The model supports researchers, caregivers, and medical professionals in accessing domain-specific information quickly.

Key Features

• Domain-Specific Knowledge: Trained on a dementia-related dataset for precise answers.
• Embeddings: Utilizes the hkunlp/instructor-large embedding model for semantic understanding.
• Retrieval-augmented QA: Employs FAISS vector databases for efficient document retrieval.
• Custom Prompting: Generates responses based on well-designed prompts to ensure factual accuracy.

---

Intended Use

• Primary Use Case: Question-answering related to dementia.
• Secondary Use Cases: Exploring dementia knowledge, aiding medical students or caregivers in understanding dementia-related topics, and supporting researchers.
• Input Format: Text queries in natural language.
• Output Format: Natural language responses relevant to the context provided.

---

Limitations

• Context Dependency: Model outputs are only as good as the context provided by the FAISS retriever. If the context is insufficient, the model may respond with "I don't know."
• Static Knowledge: The model is limited to the knowledge present in its training dataset. It may not include the latest medical breakthroughs or research after the training cutoff.
• Biases: The model might inherit biases present in the training data.

How to Use

Using the Model Programmatically

You can use the model directly in Python:

from transformers import pipeline

model_name = "rohitashva/my-llm-model"

# Load the model and tokenizer
qa_pipeline = pipeline("question-answering", model=model_name)

# Example Query
result = qa_pipeline({
    "question": "What are the symptoms of early-stage dementia?",
    "context": "Provide relevant details from a dementia dataset."
})

print(result)
