Abstract
Ensemble learning is a machine learning paradigm where many learners are jointly used to solve a problem. In this talk, I will introduce the "selective ensemble" paradigm, which is based on the recognition of "many could be better than all". That is, when a set of learners are available, using some instead of all of them to make up an ensemble may be a better choice. Then, I will introduce an application of selective ensemble to face recognition, which will illustrate that selective ensemble is a general paradigm that can be used in many disciplines, not only limited to machine learning. The essence is that when there are many potential solutions to a problem, selecting and then combining some of them may be a good choice. In this talk I will also briefly introduce some applications of ensemble learning and some ongoing research of the LAMDA group of Nanjing University.
