Overfitting on purpose: dropout, weight decay, and early stopping in one runnable lab
Machine learning tutorials often introduce overfitting as a failure mode: the model memorizes the training data, performs brilliantly on examples it has already seen, and then collapses on new data.

Expert: model capacity and overfitting trade-offs
Understanding model capacity and overfitting trade-offs is essential for designing high-performing, generalizable machine learning systems. This article explores how model capacity affects bias and variance, how overfitting manifests in deep models, and what strategies expert practitioners use to optimize complexity without sacrificing generalization.
