For Workflow: Generating Example Weights depending on label
Generating Example Weights depending on label (1)
This process uses a Generate Attribute operator for assigning new weights to examples. It uses the if condition of this operator to distinguish between labels.
This can be especially useful if you have a strong bias in your class frequency, which can harm learning. Please note that you must use a learning algorithm that supports weighted examples.
