Chapter 20

Ensembles of Learning Machines

Abstract

In this part of the book Data Science for Software Engineering: Sharing Data and Models, explores ensemble learners and multi-objective optimizers as applied to software engineering. Novel incremental ensemble learners are explained along with one of the largest ensemble learning (in effort estimation) experiments yet attempted. It turns out that the specific goals of the learning has an effect on what is learned and, for this reason, this part also explores multi-goal reasoning. We show that multi-goal optimizers can significantly improve effort estimation results.

In summary, this chapter proposes the following data analysis pattern:
