Regularization isn't just anti-overfitting — mechanisms & combo strategies for WD, Dropout, BN, Label Smoothing
Lecture 10 uses φ(x) to let linear models express nonlinear functions, then controls the resulting overfitting with train/validation/test separation, L1/L2 regularization, and model selection.
Chapter 9 presents three controls on generalization: explicit complexity penalties, optimizer-induced implicit regularization, and model selection on data excluded from training. MAP estimation then connects a Gaussian prior to an L2 penalty.
