Abstract:
The use of classifier combination has taken center stage in machine learning research, where outputs of different classifiers are combined in various ways to achieve a perceived better performance than that of any of the base classifiers involved in the combination. Many a research has however not empirically justified the use of the participating classifiers in a combination. This work looks at the usage of meta-knowledge that expresses the performance of each learning method on diverse domains to choose the most suitable learning algorithms suited for a combination for particular domains. The meta-knowledge is considered in this work is limited to the characteristics of the data involved. The approach works by having a learning algorithm that learns and describes how the data characteristics and the combined learning algorithms relate. Given a new learning domain, the domain characteristics are measured, and from the induced relationship, a selection of the most suitable base algorithms for combination will be done. The results of this work provide a fundamental step in achieving a cohesive framework for classifier combination. View full Article
