RapidMiner Decision Tree Transducer

rmtree

RapidMiner Decision Tree Transducer

Purpose

Parses the text version of a decision tree generated by RapidMiner. The decision tree is stored in a Tree object (Tree class is defined in this file). Tree class implements several output methods so that Tree can be exported to various visualization libraries.

Output -- Supported Visualizations

So far the formats expected by the following visualization libraries are supported:

• ListUI JS Library http://listui.com/?p=84>
• InfoVis JS Toolkit http://philogb.github.com/jit/
• d3 JS Vis Library http://d3js.org/

Usage

$ python rmtree.py rmtree.txt 

About

Script to transform a decision tree produced by RapidMiner (rmtree.txt) to an HTML table in the format expected by the JS library ListUI.

The decision tree, obviously, has to be in text format. Go to "Text View" and copy+paste the text of the tree to a file, then pass that file to this script.

Script stores this decision tree internally as a Tree object. The Tree class, defined in this file, provides multiple output methods: simple JSON (which is returned by Tree.repr() and Tree.str()), and also a couple of JSON formats expected by popular visualization libaries (see above).
