class kumoai.encoder.MinLogNumerical

Bases: Encoder

A MinLogNumerical encoder encodes its corresponding numerical column, after applying the transformation

\[\log \left( \frac{\text{feature} - (\text{max} + 1)}{-1.0} \right)\]

and using a strategy for null value imputation specified by na_strategy.

na_strategy: Literal[zero, mean, separate, raise] = 'mean'

The specified null value imputation strategy.
