Post date: Jan 31, 2015 3:13:06 PM

There are several techniques to harness the decision tree to work as we desire.

- Removing misclassified instances from the training set and rebuild the tree until no misclassified instances left. -- refer to Page 332, section "Improving Decision Trees" -- Chapter 7: Data Transformations, Data Mining: Practical Machine Learning Tools and Techniques.

- Tree pruning: there are at least two ways to prune the tree (to get rid of overfitting effects) -- refer to wiki.
