Défis Machine Learning Fundamentals

Machine Learning Fundamentals challenges put you inside the work of turning raw data into models that hold up. You'll develop skills in Supervised Learning, Classification & Regression, and Feature engineering, then validate your work with Train/Test Split and Cross-validation in scikit-learn.

From there you'll handle the harder edges — Hyperparameter tuning, Tree ensembles, Model Calibration, and Model selection under business constraints — moving toward Production model tuning and Feature pipelines the way working ML teams do. Each challenge you solve earns a verified credential you can share with recruiters.
