Intro to Machine Learning ↗

The fastest hands-on introduction to machine learning — 3 hours from zero to building your first model. Kaggle’s browser-based notebooks mean no setup required, and the 30 free GPU hours per week let you experiment immediately. Covers decision trees, model validation, underfitting/overfitting, and random forests with real datasets. Take this if you want to get your hands dirty with ML code in an afternoon, not a semester.
