CHAPTER 16

Writing New Learning Schemes

Suppose you need to implement a special-purpose learning algorithm that is not included in Weka. Or suppose you are engaged in machine learning research and want to investigate a new learning scheme. Or suppose you just want to learn more about the inner workings of an induction algorithm by actually programming it yourself. This section uses a simple example to show how to make full use of Weka’s class hierarchy when writing classifiers.

Weka includes the elementary learning schemes listed in Table 16.1, mainly for educational purposes. None take any scheme-specific command-line options. They are all useful for understanding the inner workings of a classifier. As an example, we describe the weka.classifiers.trees.Id3 ...
