问题 I am new to Rapid Miner and using SVM Linear in it. My model is as: I made Training Example set which consist of 3552 examples and just 2 attributes and I am doing nominal to numeric conversion, passing through SVM Linear model and then connecting model output in applying model. This is fine. In Test Example set, I have 735 examples with 2 attributes and doing nominal to numeric conversion and then applying this converted Example set to Applying Model. At this stage I am getting an error when

问题 I'm using Rapidminer to do an analysis. I used cross-validation on several models to get the best working model. Now I want to use this model to test on a separate testset that I made using Split Data to estimate the performance. How do I use the test set? As far as I can tell, all the validation modules use the training set that the model was made on. Which performance measure can I use that takes in a model and my test set? 回答1: Use the "Apply Model" operator with your model as the first
