smoothing¶
Available in Data Preparation for Target Encoding
Description¶
The smoothing value is used for blending and to calculate lambda. Smoothing controls the rate of transition between the particular level’s posterior probability and the prior probability. For smoothing values approaching infinity, it becomes a hard threshold between the posterior and the prior probability. This value defaults to 20.
