Class GaussianNaiveBayesModel

java.lang.Object

org.apache.ignite.ml.naivebayes.gaussian.GaussianNaiveBayesModel

All Implemented Interfaces:

Serializable, AutoCloseable, Exportable<GaussianNaiveBayesModel>, IgniteModel<Vector,Double>, Model<Vector,Double>

Deprecated.

The ignite-ml module is deprecated and will be removed in a future release. Use the ignite-ml-ext Apache Ignite extension or the standalone GridGain ML package instead.

@Deprecated
public final class GaussianNaiveBayesModel
extends Object
implements IgniteModel<Vector,Double>, Exportable<GaussianNaiveBayesModel>, Serializable

Simple naive Bayes model which predicts result value y belongs to a class C_k, k in [0..K] as p(C_k,y) = p(C_k)*p(y_1,C_k) *...*p(y_n,C_k) / p(y). Return the number of the most possible class.
