scaleType property

String? scaleType
getter/setter pair

How the parameter should be scaled to the hypercube.

Leave unset for categorical parameters. Some kind of scaling is strongly recommended for real or integral parameters (e.g., UNIT_LINEAR_SCALE).

Optional. Possible string values are:

  • "NONE" : By default, no scaling is applied.
  • "UNIT_LINEAR_SCALE" : Scales the feasible space to (0, 1) linearly.
  • "UNIT_LOG_SCALE" : Scales the feasible space logarithmically to (0, 1). The entire feasible space must be strictly positive.
  • "UNIT_REVERSE_LOG_SCALE" : Scales the feasible space "reverse" logarithmically to (0, 1). The result is that values close to the top of the feasible space are spread out more than points near the bottom. The entire feasible space must be strictly positive.
