SmartPlate – AI Nutrition Assistant

Photograph your meal and get instant nutritional analysis with evidence-based health advice from WHO, DGE, and Harvard guidelines.

How it works

1. 📷 Computer Vision — A Vision Transformer (ViT) fine-tuned on Food-101 classifies the dish (20 classes, 96.46% accuracy)
2. 🔢 ML Numeric — Logistic Regression classifies the dish as healthy/medium/unhealthy based on nutritional values (100% test accuracy)
3. 💬 NLP RAG — OpenAI gpt-4o-mini generates evidence-based advice from a vector store (ChromaDB) of WHO/DGE/Harvard nutrition guidelines
