| 摘 要： | 如何在测试节点里构造一个恰当的分割超平面是构造决策树的关键,与单变量决策树不同,多变量(倾斜)决策树可以找到与特征轴不垂直的超平面。本文将从几何学角度说明构造测试节点的过程,提出了一种两阶段决策树的算法。 |
| 关 键 词： | 超平面 两阶段 决策树 |

| Abstract: | How to construct an appropriate partitioning hyperplane in test node is the key to construct a decision tree.Different from decision tree with a single variable,the multi-variable（tilted） decision tree can find a hyperplane which is not perpendicular to the characteristic shaft.This paper will explain the process of constructing the test node and propose a two-stage decision tree algorithm. |
| Keywords: | hyperplane two stages decision tree |
