java.lang.Object

ai.libs.jaicore.ml.ranking.dyad.learner.util.AbstractDyadScaler

ai.libs.jaicore.ml.ranking.dyad.learner.util.DyadStandardScaler

All Implemented Interfaces:

java.io.Serializable

public class DyadStandardScaler
extends AbstractDyadScaler

A scaler that can be fit to a certain dataset and then be used to standardize datasets, i.e. transform the data to have a mean of 0 and a standard deviation of 1 according to the data it was fit to.

transformInstances

public void transformInstances(org.api4.java.ai.ml.ranking.dyad.dataset.IDyad dyad,
                               java.util.List<java.lang.Integer> ignoredIndices)

Description copied from class: AbstractDyadScaler

Transforms only the instances of each dyad according to the mean and standard deviation of the data the scaler has been fit to. The attributes with indices contained in ignoredIndices are not transformed. {

Specified by:

transformInstances in class AbstractDyadScaler

ignoredIndices - The List of indices that are been ignored by the scaler.

transformAlternatives

public void transformAlternatives(org.api4.java.ai.ml.ranking.dyad.dataset.IDyad dyad,
                                  java.util.List<java.lang.Integer> ignoredIndices)

Description copied from class: AbstractDyadScaler

Transforms only the alternatives of each dyad according to the mean and standard deviation of the data the scaler has been fit to.

Specified by:

transformAlternatives in class AbstractDyadScaler

ignoredIndices - The List of indices that are been ignored by the scaler.

transformInstaceVector

public void transformInstaceVector(org.api4.java.common.math.IVector vector,
                                   java.util.List<java.lang.Integer> ignoredIndices)

Description copied from class: AbstractDyadScaler

Transforms an instance feature vector.
