Rule induction in Eminer

Hi guys,

Can anyone please tell me how to see the decision tree (the tree diagram with the leaves and so on) Eminer creates when you execute the rule induction node in Eminer version 6.1? When I access the results, I only seem to find information on the performance measures such as the misclassification rate, ASE, etc. Thanks guys!

Hi Jake,

Newer versions of Enterprise Miner have the option to use the decision tree node to import a tree model ... we could plan a workaround with EM13.1 or newer.

For EM 6.1 I think the easiest might be to use a decision tree with the same settings of the proc arbor that runs in the rule induction node.

From the log, I got:

Decision Tree Node Option	Value
Leaf Size	50
Minimum Categorical Size	5 (default)
Maximum Depth	4
Missing Values	Use in Search (default)
Nominal Target Criterion	Gini
Assessment measure	Average Square Error

I got a slightly better model, so I may be missing one more option. Hopefully someone will come to the rescue!

In the meantime this should get you close enough.

Good luck!

Miguel

Thanks Miguel,

I have been using Decision Tree Nodes in EM 6.1 as surrogate models to check the output of the rule induction node. Thus far it seems to do the trick. I just thought there might be an easier point-and-click method. Thanks for the help!

It is definitely a good suggestion. I will forward it to in product management.

Any more suggestions please send them our way.

Thanks Jakes!
