可视化Weka分类树 [英] Visualizing Weka classification tree

问题描述

我正在使用一些在线可用的数据集，并试图可视化树。但是，它根本不让我看到树选项。有人可以指导我如何通过使用在线提供的数据集来获取weka中的树形图吗？

I am using few data sets available online and trying to visualize tree. However, it does not let me visualize tree option at all. Could anyone please guide me how to get the tree diagram in weka by using data sets available online?

解决方案

Look here http://maya.cs.depaul.edu/classes/ect584/weka/classify.html, for example.

First you have to fit your decision tree (I used the J48 classifier on the iris dataset), in the usual way. In the results list panel (bottom left on Weka explorer), right click on the corresponding output and select "Visualize tree" as shown below.

If you have installed the Prefuse plugin, you can even visualize your tree on a more pretty layout.
