Summary

A containerized, full-stack clinical risk screening platform on Hugging Face Spaces. Three scikit-learn classifiers screen for diabetes, stroke and heart disease across 30 clinical inputs, and Llama 3.1 8B on Groq explains each result in accessible language. Published as a research preprint on Zenodo in May 2026.1Live demo on Hugging FaceInteractive Demo · huggingface.co

Problem

A bare 'Diabetic / Not diabetic' output raises more questions than it answers for anyone without a medical or machine-learning background.1Live demo on Hugging FaceInteractive Demo · huggingface.co

Architecture

SVM, Random Forest and Logistic Regression behind one FastAPI service; Llama 3.1 explains each result

01Three disease models
An SVM for diabetes, a Random Forest for stroke and Logistic Regression for heart disease, each in its own scikit-learn pipeline.
02One FastAPI service
A single FastAPI backend serves the web interface, the prediction endpoints and the AI assistant with no frontend build step, containerized with Docker.
03Contextual explanations
Patient inputs and model outputs go to Llama 3.1 8B on Groq, which explains the result in plain language and answers follow-up questions.

Not claimed

Can it diagnose me?: No source says it diagnoses anything, so I won't say it does. It's a screening tool that explains risk. For a diagnosis, see a doctor.
