Setup Error Performance Operator
I updated my rapidminer to 5.3.008 and the following does not work anymore
I am using cross validation operator to split the data into testing and training..I use a decision tree for training and in testing section I use the Applymodel generated by the decision tree and check the performance.
1.Use X Validation Operator to a dataset
2.Use decision tree in training section
3.Use Apply Model and Performance in the testing set.
4.Run the program
I am getting the following error , setup does not have any obvious error but you should check log for detailed message and in the logs I see the following:
