决策树的剪枝是将生成的树进行简化，以避免过拟合。在决策树完美分割学习样例之前，停止决策树的生长。这种提早停止树生长的方法，称为预剪枝方法。在构造决策树的同时进行剪枝。所有决策树的构建方法，都是在无法进一步降低熵的情况下才会停止创建分支的过程，为了避免过拟合，可以设定一个阈值，熵减小的数...

Obesity is a major global health crisis, and machine learning techniques show promise for predicting and understanding the factors that contribute to it. This study explores the application of decision tree algorithms with various pruning strategies for predicting obesity. The dataset used in this ...
Each node of the tree has 0 or c children. The C-fuzzy decision tree learning process is performed according to Algorithm 1. This version of tree learning algorithm is a modification of traditional version, presented in Pedrycz and Sosnowski (2005)—it includes randomness aspect, used in C-...
Generating the decision tree in two distinct phases could result in a substantial amount of wasted effort since an entiresubtree constructed in the first phase may later be pruned in the next phase. In this paper, we propose PUBLIC, an improveddecision tree classifier that integrates the second ...
