Performance (Classification) question
Next comes the process, interrupted too long by Performance error messages. This is the latest bad thing: Missing label. Input Example Set does not have a label attribute. I checked the Set Role operator Parameters has an Attribute that is a Label.
I ran once more. Now I get Non-nominal label. The label attribute (Purchases_Frequency) must be nominal for the calculation of performance criteria for classification tasks.
I really want to see this through, to prove Performance (Classification) is worth all this time. Please send me some helpful suggestions. Thanks for your time.
