摘要
En 中文
Piecewise linear regression is a powerful and flexible regression technique where the dataset is divided into disjoint partitions and a separate regression is computed for each partition. Here, we consider the piecewise linear regression problem where the data partitioning is performed via a fixed number of break points on a predetermined dimension. We develop a column generation heuristic based on a set partitioning formulation of the problem and evaluate its prediction performance using a mixed integer programming formulation introduced earlier as a benchmark. Our results show that the proposed heuristic displays an efficient and robust performance, and also scales up smoothly as the dataset grows.
