摘要
提出了一种决策树自动生成的方法,介绍了其阈值确定方法、数据结构、决策树生成流程,给出了一个自动生成的实例,并与人工生成的决策树进行了比较。
An algorithm, by which a bi-decision tree of classification is generated automatically according to the distribution of targets in feature spaces, is proposed. The method of selecting threshold, data structures and flow of the algorithm are introduced. An example is shown and compared with man-made tree, both of them are generated on the same condition.
