[SOLVED] evaluation of resampled dataset
Hello everyone!
This is my first post, so first things first. This is a great peace of software and you guys deserves nobel price for making it free for community. THANK YOU.
Now, here is my question, probably little stupid but I want to be sure. So I have unbalanced dataset, so I overcome this by undersampling majority class, or by applying weights or somehow make it balanced for training. But I must evaluate the performance, by cross-validation or split validation on original unbalanced dataset ,right? The balanced part is only for training, right?
Thank you in advance.
