NHotWeightedEncoder

object NHotWeightedEncoder extends SettingsBuilder with Serializable

Transform a collection of weighted categorical features to columns of weight sums, with at most N values.

Weights of the same labels in a row are summed instead of 1.0 as is the case with the normal NHotEncoder.

Missing values are either transformed to zero vectors or encoded as a missing value.

When using aggregated feature summary from a previous session, unseen labels are either transformed to zero vectors or encoded as unknown (if encodeMissingValue is true) and [FeatureRejection.Unseen]] rejections are reported.
