org.nd4j.linalg.api.ops.impl.transforms.comparison.CompareAndReplace

All Implemented Interfaces:

Op, TransformOp

public class CompareAndReplace
extends BaseTransformOp

Element-wise Compare-and-Replace implementation as Op Basically this op does the same as Compare-and-Set, but op.X is checked against Condition instead

Constructor Summary

Constructors

Constructor and Description
CompareAndReplace()
CompareAndReplace(INDArray x, INDArray y, Condition condition) With this constructor, op will check each X element against given Condition, and if condition met, element Z will be set to Y value, and X otherwise PLEASE NOTE: X will be modified inplace.
CompareAndReplace(INDArray x, INDArray y, INDArray z, Condition condition) With this constructor, op will check each X element against given Condition, and if condition met, element Z will be set to Y value, and X otherwise Pseudocode: z[i] = condition(x[i]) ? y[i] : x[i];
CompareAndReplace(SameDiff sameDiff, SDVariable to, SDVariable from, Condition condition)
