How to give different weight to each class before prediction

Dear ALL
I have a dataset with three unbalanced classes. How can I give more weights to classes with less example numbers?

Hi,

you generate a new attribute and set its role to weight.

Best,

You can also use the Generate Weight (Stratification) operator to do this automatically.  Check out its tutorial process to see this.
