DML_ACTIVATION_IDENTITY_OPERATOR_DESC structure (directml.h)

Performs the identity activation, effectively copying every element of InputTensor to the corresponding element of OutputTensor.

f(x) = x

This operator supports in-place execution, meaning that the output tensor is permitted to alias InputTensor during binding.

Syntax

struct DML_ACTIVATION_IDENTITY_OPERATOR_DESC {
  const DML_TENSOR_DESC *InputTensor;
  const DML_TENSOR_DESC *OutputTensor;
};

Members

InputTensor

Type: const DML_TENSOR_DESC*

The output tensor to write the results to.

OutputTensor

Type: const DML_TENSOR_DESC*

A pointer to a constant DML_TENSOR_DESC containing the description of the tensor to write the results to.

Availability

This operator was introduced in DML_FEATURE_LEVEL_1_0.

Tensor constraints

InputTensor and OutputTensor must have the same DataType, DimensionCount, and Sizes.
