Optimizing decision tree Score performance by feature loop selection

Dear All ,
I’m new in KNIME , I need your help , Please look at the below screen-shot work-flow:

In order to improve the performance of Decision tree model , I select in the feature selection method : Backward feature elimination

I got through the work flow , Until I reach the finals step of the score I got the following score:

I used the Filter selection loop to know the best features use to optimize the accuracy of the model (decision tree) to the best mark until I get the following result:

Of course I go to select the features based on the recommendation (best score) of the feature selection loop but finally I got another bad performance results again as the following:

I share with you the content of the workflow and the DB here :

Can any one tell me how to reach the best performance level (82 %) as it shown above ?

Hi @MAAbdullah47

Please mind it’s weekend and activity is usually low during these times (and this is a community, not a consultancy firm).

I’m not into decision tree nodes so will have to pass on this one.


Hi @MAAbdullah47

You haven’t used the same static seed in the two partitioning nodes. please check the “Use random seed” box and make sure to have the same number there in both nodes, then the accuracy is going to be the same.
