Class BaseElementWiseOp

java.lang.Object

org.nd4j.linalg.ops.BaseElementWiseOp

All Implemented Interfaces:

ElementWiseOp

Direct Known Subclasses:

Abs, BaseTwoArrayElementWiseOp, EqualTo, Exp, Floor, GreaterThan, HardTanh, Identity, LessThan, Log, Max, MaxOut, Negative, Pow, Round, Sigmoid, Sign, Sqrt, Stabilize, Tanh

public abstract class BaseElementWiseOp
extends Object
implements ElementWiseOp

Baseline element wise operation so only applyTransformToOrigin has to be implemented. This also handles the ability to perform scalar wise operations vs just a functional transformation
