Classification (also known as classification trees or decision trees) is a data mining algorithm that creates a step-by-step guide for how to determine the output of a new data instance.
分类(也即分类树或决策树)是一种数据挖掘算法，为如何确定一个新的数据实例的输出创建逐步指导。
For example, in a classification problem, the learner approximates a function mapping a vector into classes by looking at input-output examples of the function.
在一个分类问题上，学习者模拟一个函数将通过查将找输入输出的用例向量映射为相应的类。
