Class BinarizationPreprocessor<K,V>

java.lang.Object

org.apache.ignite.ml.preprocessing.binarization.BinarizationPreprocessor<K,V>

Type Parameters:

K - Type of a key in upstream data.

V - Type of a value in upstream data.

All Implemented Interfaces:

Serializable, BiFunction<K,V,LabeledVector>, DeployableObject, IgniteBiFunction<K,V,LabeledVector>, Preprocessor<K,V>

public final class BinarizationPreprocessor<K,V>
extends Object
implements Preprocessor<K,V>, DeployableObject

Preprocessing function that makes binarization. Feature values greater than the threshold are binarized to 1.0; values equal to or less than the threshold are binarized to 0.0.
