Piecewise Linear Models
SL AI 2.5
We use a piecewise linear model when different linear models apply over different parts of the domain of points. Basically, a piecewise linear model is a collection of smaller, domain-restricted models.
We write piecewise functions with the following notation:
f(x)={g(x),a<x<bh(x),b≤x<c
