AI-Powered Medical Risk & Disease Prediction System

Overview

This system provides AI-powered medical risk assessment using supervised machine learning. It analyzes patient data to predict overall risk levels and disease probabilities with explainable recommendations.

Features

• Risk Classification: Predicts Low/Medium/High risk levels
• Risk Regression: Calculates disease risk percentage (0-100%)
• Feature Engineering: Medical logic-based feature extraction
• Explainable AI: Provides reasoning for predictions
• Web Interface: Simple HTML/CSS/JS frontend
• FastAPI Backend: RESTful API with validation
