Many regression and classification procedures fit a parameterized function $f(x;w)$ of predictor variables $x$ to data $\{x_{i}, y_{i}\}_1^N$ based on some loss criterion $L(y, f)$.

General regression and classification models are constructed as linear combinations of simple rules derived from the data.
