🚀 NASA Bioscience AI Assistant (Lightweight)

A lightweight AI assistant specialized in NASA space biology research, optimized to stay within Hugging Face's 1GB storage limit while providing detailed explanations.

✨ Lightweight Features

• 🧠 Optimized Model: Uses DistilBERT instead of large DialoGPT
• 📚 Full Knowledge Base: 5,148 NASA research chunks
• 🔍 Advanced RAG: FAISS vector search with semantic similarity
• 📊 Detailed Explanations: Comprehensive responses with scientific context
• 🎯 Query Classification: Automatic detection and adaptation
• 📖 Source Citations: Research papers with confidence scores
• 💾 Storage Optimized: Under 1GB total size

🚀 Example Queries

• "What is microgravity and how does it affect biological systems?"
• "How does space affect bone density and muscle mass?"
• "What are the comprehensive effects of space radiation?"
• "How do plants grow and respond in microgravity?"
• "What countermeasures exist for space-related health issues?"

🔬 How It Works

1. Lightweight Model: DistilBERT for summarization (much smaller than DialoGPT)
2. RAG System: Retrieves relevant research using FAISS vector search
3. Intelligent Templates: Provides structured, detailed explanations
4. Multi-Source Integration: Combines 8 research papers per query
5. Scientific Accuracy: Based on real NASA research data

📊 Storage Optimization

• Model Size: ~250MB (DistilBERT vs 1.35GB DialoGPT)
• RAG Index: ~50MB (FAISS + chunks)
• Total Size: Under 400MB (well within 1GB limit)
• Performance: Maintains high-quality responses

💡 Usage

Simply type your question about space biology, and the AI will provide a detailed, comprehensive answer with:

• Scientific explanations and mechanisms
• Clinical implications and data
• Source citations from NASA research
• Confidence scores and research context

Perfect for researchers, students, and space enthusiasts! 🌟
