The supervised learning loop: fit a model on training data, predict on held-out data, evaluate, then diagnose bias vs. variance to tune complexity.

What to study

  • โœ“Bias-variance tradeoff, overfitting/underfitting, and train/validation/test splits with cross-validation
  • โœ“Linear and logistic regression: cost functions, gradient descent, and decision boundaries
  • โœ“Regularization (L1/L2) and feature scaling to control model complexity
  • โœ“Evaluation metrics: MSE/Rยฒ for regression, accuracy/precision/recall/confusion matrix for classification
