Feature selection is a crucial but often overlooked step in machine learning that involves identifying and retaining only the most relevant input variables for a model. Including irrelevant features can lead to several problems, including increased training time, overfitting, obscured predictive signals, and reduced model interpretability. Techniques for feature selection fall into three main categories: filter methods, wrapper methods, and embedded methods, each offering different trade-offs between speed, accuracy, and the ability to capture feature interactions.
