Delphi 🔮

An autonomous AI data science agent. Ask a question about the future, and Delphi finds the data, trains the best model, explains why, and tells you the story.

Built at WildHacks 2026 — Northwestern University

What it does

1. You ask a question — "Predict diabetes risk based on patient health indicators"
2. AI agent finds data — Searches Kaggle, HuggingFace, and World Bank APIs
3. Databricks processes it — Spark cleaning, feature engineering, Delta Lake storage
4. Model arena trains 5 models — XGBoost, LightGBM, Random Forest, Linear, SVM — tracked with MLflow
5. SHAP explains — Feature importance and model explainability
6. ElevenLabs narrates — A voice data story summarizes the findings
