Project Description

induce classification rules (decision trees) from examples

C4.5 is a software extension of the basic ID3 algorithm designed by Quinlan to address the following issues not dealt with by ID3:

* Avoiding overfitting the data o Determining how deeply to grow a decision tree. * Reduced error pruning. * Rule post-pruning. * Handling continuous attributes. o e.g., temperature * Choosing an appropriate attribute selection measure. * Handling training data with missing attribute values. * Handling attributes with differing costs. * Improving computational efficiency.
