Clamp¶

General¶

Clamp operation represents clipping activation function, it applies following formula on every element of \(\src\) tensor (the variable names follow the standard Naming Conventions):

\[clamp(src_i) = min(max(src_i, min\_value), max\_value)\]

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

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`	Required

Outputs¶

Index	Argument Name	Required or Optional
0	`dst`	Required

Supported data types¶

Clamp operation supports the following data type combinations.

Src	Dst
f32	f32
f16	f16
bf16	bf16
