water.Iced

hex.Model.Parameters

hex.SupervisedModel.SupervisedParameters

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, Freezable

Enclosing class:

SupervisedModel<M extends Model<M,P,O>,P extends SupervisedModel.SupervisedParameters,O extends SupervisedModel.SupervisedOutput>

public abstract static class SupervisedModel.SupervisedParameters
extends Model.Parameters

Supervised Model Parameters includes a response column, and whether or not rebalancing classes is desirable. Also includes a bunch of cheap cached convenience fields.

Field Summary

Fields

Modifier and Type	Field and Description
boolean	_balance_classes Should the minority classes be upsampled to balance the class distribution?
float	_max_after_balance_size When classes are being balanced, limit the resulting dataset size to the specified multiple of the original dataset size.
java.lang.String	_response_column Supervised models have an expected response they get to train with!
boolean	_toEnum Convert the response column to an enum (forcing a classification instead of a regression) as needed.

Field Detail

_response_column

public java.lang.String _response_column

Supervised models have an expected response they get to train with!

_toEnum

public boolean _toEnum

Convert the response column to an enum (forcing a classification instead of a regression) as needed. The default is false, which means "do nothing" - accept the response column as-is and that alone drives the decision to do a classification vs regression.

_balance_classes

public boolean _balance_classes

Should the minority classes be upsampled to balance the class distribution?

_max_after_balance_size

public float _max_after_balance_size

When classes are being balanced, limit the resulting dataset size to the specified multiple of the original dataset size. Maximum relative size of the training data after balancing class counts (can be less than 1.0)
