Class LossNegativeLogLikelihood

java.lang.Object

org.nd4j.autodiff.functions.DifferentialFunction

org.nd4j.linalg.lossfunctions.impl.LossMCXENT

org.nd4j.linalg.lossfunctions.impl.LossNegativeLogLikelihood

All Implemented Interfaces:

Serializable, ILossFunction

public class LossNegativeLogLikelihood
extends LossMCXENT

Negative log likelihood loss function

In practice, this is implemented as an alias for LossMCXENT due to the mathematical equivalence
