Pruning decision trees is deemed an effective way of solving over-fitting in practice. Pruned decision trees usually have simpler structure and are expected to have higher generalization ability at the expense of classification accuracy. Nowadays, various pruning methods are available. However, the problem of how to make a trade-off between structural simplicity and classification accuracy has not been well solved. In this paper, we firstly propose a method to evaluate structural complexities… CONTINUE READING
