Module Modelkit.Ordinal_encoder

Encoding of finite float64 categories as ordered integer-valued columns.

Each feature's categories are sorted ascending and encoded from zero. Unknown values either fail or map to a caller-selected finite value that must not collide with a learned integer code. Sample weights are rejected.

type unknown_category =
  1. | Reject
  2. | Use_encoded_value of float
type params = {
  1. unknown_category : unknown_category;
}
