DML_ELEMENT_WISE_THRESHOLD_OPERATOR_DESC structure (directml.h)

Replaces all elements of InputTensor below the given threshold, Min, with Min. Results are placed into the corresponding element of OutputTensor.

f(x) = max(x, Min)

Where max(a,b) returns the larger of the two values a,b.

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

Syntax

struct DML_ELEMENT_WISE_THRESHOLD_OPERATOR_DESC {
  const DML_TENSOR_DESC *InputTensor;
  const DML_TENSOR_DESC *OutputTensor;
  const DML_SCALE_BIAS  *ScaleBias;
  FLOAT                 Min;
};

Members

InputTensor

Type: const DML_TENSOR_DESC*

The input tensor to read from.

OutputTensor

Type: const DML_TENSOR_DESC*

The output tensor to write the results to.

ScaleBias

Type: _Maybenull_ const DML_SCALE_BIAS*

An optional scale and bias to apply to the input. If present, this has the effect of applying the function g(x) = x * scale + bias to each input element prior to computing this operator.

Min

Type: FLOAT

The minimum value, below which the operator replaces the value with Min.

Availability

This operator was introduced in DML_FEATURE_LEVEL_1_0.

Tensor constraints

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