Decision Tree Result not showing

AgusKrisn4

When i run it, it's only showing perfomance vector, attribute weights, and example set, the decision tree result not showing. Before i'm using optimize selection (evolutionary), it worked just fine

here my model's screenshot


Here inside the optimize selection (evolutionary)


Here inside Split Validation

Hi!

The feature selection is not supposed to show you a model. It tries a lot of different models.

Just put a Decision Tree after the selection, it will be built on the selected attributes.

The best approach is to put the feature selection into a cross validation (yes, then you'll have an "outer" and an "inner" validation). You will get a good estimation for the accuracy of the entire modeling process that way. 

Inside the cross validation:

Left: Feature selection (evolutionary), Decision Tree
Right: Apply Model, Performance

Balázs

Hi,

The operator you are using will give you the most important features for what you want to use the data for; classification, regression, etc. So you have to use the new dataset at the output to do your prediction with the Decision Tree.

Or you can use the "Optimize Parameters (Evolutionary)" under Modeling > Optimization > Parameters, that will give the tree model in addition. I hope will help somehow.

Regards.
