Model Questions

Hi, everyone. After I learned from the resources, I have a few questions.
1. Why "Apply Preprocessing" is added? What is the function?

2. Why "Group Models" is added here? Why "pre" connects to "mod"?

Thanks for giving answers.

Hi @karen1015,

1- I assume that your model is inside of a cross validation operator.

In this case, the apply preprocessing operator takes the model used to normalize the training set and then apply the model for denormalize the test data, to avoid biases into the model.

2- The pre output port from Normalize operator contains the model used to normalize the dataset.

Best,

Cesar
