Clamp

Versioned name: Clamp-1

Category: Activation function

Short description: Clamp operation represents clipping activation function.

Attributes:

• min
• Description: min is 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. For example, min equal 10 means that any value in the input that is smaller than the bound, is replaced by 10.
• Range of values: non-negative positive floating point number
• Type: float
• Default value: None
• Required: yes
• max
• Description: max is 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. For example, max equals 50 means that any value in the input that is greater than the bound, is replaced by 50.
• Range of values: positive floating point number
• Type: float
• Default value: None
• Required: yes

Inputs:

• 1: Multidimensional input tensor. Required.

Outputs:

• 1: Multidimensional output tensor with shape and type matching the input tensor.

Detailed description:

Clamp does the following with the input tensor element-wise:

$clamp( x )=\left\{\begin{array}{ll} max\_value \quad \mbox{if } \quad input( x )>max\_value \\ min\_value \quad \mbox{if } \quad input( x ) \end{array}\right.$

Example

<layer ... type="Clamp" ... >
<data min="10" max="50" />
<input> ... </input>
<output> ... </output>
</layer>
