blending

  • Available in: Target Encoding

Description

The blending parameter defines whether the target average should be weighted based on the count of the group. It is often the case that some groups may have a small number of records and the target average will be unreliable. To prevent this, the blended average takes a weighted average of the group’s target value and the global target value.
