ClampBackward

General

ClampBackward operation computes gradient for Clamp.

Operation attributes

Attribute Name	Description	Value Type	Supported Values	Required or Optional
min	The lower bound of values in the output. Any value in the input that is smaller than the bound, is replaced with the min value.	f32	Arbitrary valid f32 value	Required
max	The upper bound of values in the output. Any value in the input that is greater than the bound, is replaced with the max value.	f32	Arbitrary valid f32 value	Required
use_dst	If true, use dst of Clamp operation to calculate the gradient. Otherwise, use src .	bool	true (default), false	Optional

Execution arguments

The inputs and outputs must be provided according to below index order when constructing an operation.

Inputs

Index	Argument Name	Required or Optional
0	src / dst	Required
1	diff_dst	Required

Outputs

Index	Argument Name	Required or Optional
0	diff_src	Required

Supported data types

ClampBackward operation supports the following data type combinations.

Src / Dst	Diff_dst	Diff_src
f32	f32	f32
f16	f16	f16
bf16	bf16	bf16

Implementation Notes

ClampBackward supports in-place operations, meaning that diff_dst can be used as both input and output (diff_src). In case of in-place operation, the original diff_dst data will be overwritten. Use in-place operations whenever possible for performance.
