decision_tree_algorithm's Introduction

Decision_Tree_algorithm

决策树的主要优势就在于数据形式非常容易理解

决策树的优点:计算复杂度不高,输出结果易于理解,对中间值的缺失不敏感,可以处理不相关特征数据 缺点:可能会产生过度匹配问题。 离散型和连续性数据都可以处理。

在构建决策树时,我们需要解决的第一问题就是,当前数据集上哪个特征在划分数据分类时起决定性作用。 为了找到决定性的特征,划分出最好的结果,我们必须评估每个特征。完成测试之后,原始数据集就被划 分成几个数据子集。这些数据子集会分布在第一个决策点的所有分支上,如果某个分支下的数据属于同一 类型,则不必继续分割,否则继续分割。直到所有分支无法分割。
