kumoai.encoder.Hash

class kumoai.encoder.Hash

Bases: Encoder

A Hash encoder encodes its corresponding categorical column by hashing each value to range [0..num_components], and using this hashed value to determine the corresponding embedding (with size channels from the model plan).

num_components: PositiveInt

The number of distinct categories after hashing.

na_strategy: Literal[separate, most_frequent] = 'separate'

The specified null value imputation strategy.
