Alternately, you can also import a previously trained model on an existing tree instance, assuming the features & class are the same: var treeJson = dt.toJSON(); dt.import(treeJson); Install npm idecision-tree Repository github.com/serendipious/nodejs-decision-tree-id3 ...
决策树 (decision tree) 内容学习于ApacheCN github 定义: 分类决策树模型是一种描述对实例进行分类的树形结构。决策树由结点(node)和有向边(directed edge)组成。结点有两种类型:内部结点(internal node)和叶结点(leaf node)。内部结点表示一个特征或属性(features),叶结点表示一个类(labels)。

The entire process at GitHub summarized as a flowchart. (Large preview) So whenever a debate comes up, document your decisions in a decision tree. Turn them into posters. Place them in kitchen areas and developer’s and QA workspaces. Put them in design critique rooms.Make them visiblewhere...

the decision tree. It is also possible to use thegraphvizlibrary for visualizing the decision trees, however, the outcome is very similar, with the same set of elements as the graph above. That is why we will skip it here, but you can find the implementation in theNotebook on GitHub. ...
