In this tutorial, we will learn about the decision tree algorithm in machine learning. By Basantjeet Das Last updated : April 16, 2023 What is Decision Tree Algorithm?A decision tree is a tree-like structure or graph based on decisions and their possible consequences to a situation. In ...
Decision tree algorithm is a classic algorithm series in machine learning. It can be used as both a classification algorithm and a regression algorithm, and is also particularly suitable for integrated learning such as random forests. This article summarizes the principle of decision tree algorithm. ...

A greedy algorithm, as the name suggests, always makes the choice that seems to bethe best at that moment(当下最好的选择,未必 长远最好的选择 =》 目光短浅:better, not the best)。 how? each iteration, iterates through the veryunused attribute(未被使用的属性)of the set S andcalculates Ent...

1:最优Decision Tree是NP难题,所以使用的Decision-Tree算法都是基于启发式(Heuristic)算法,如Greedy Algorithm等,在每个节点判断都是根据局部最优解来进行操作。启发式算法不能保证返回全局最优的Decision Tree。 2:容易产生过于复杂的树,不能很好地获得数据的通用模型,这个实际上是被称为是Overfitting,剪枝技术能够很好...
