Re: Enable ID3 visualization in WEKA

> Good evening, I'm a student here in Brazil and we are using Weka at the university. When we use the ID3 algorithm, it is not possible to view the generated decision tree. Is there a way to enable this option (which is available in J48), just for educational purposes?

Unfortunately, no as it would require a code change. Only classifiers
that implement the Drawable interface (and have actual
implementations) can be displayed like that:
https://weka.sourceforge.io/doc.dev/weka/core/Drawable.html

And Id3 does not implement that interface:
https://weka.sourceforge.io/doc.packages/simpleEducationalLearningSchemes/weka/classifiers/trees/Id3.html
