The discussion of tree training and pruning is still more or less slanted toward the large trees.

所论述的整形和修剪，或多或少仍倾向于大冠树。

Horticulture is the science of growing plants. It involves plant propagation (the reproduction of plants) and pruning and training plants.

园艺是种植植物的科学，包括植物繁殖，植物的修剪和整枝。

By using the method to improve the ID3 algorithm, experiments show that the algorithm generates smaller decision tree and USES less training time than the algorithm using pre-pruning method.

利用该方法对基本ID 3决策树算法进行了改进。分析和实验表明，与先剪枝方法相比，该方法能进一步减小决策树的规模和训练时间。
