Clamp#
Versioned name: Clamp-1
Category: Activation function
Short description: Clamp operation represents clipping activation function.
Detailed description:
Clamp performs clipping operation over the input tensor element-wise. Element values of the output are within the range [min, max]
.
Input values that are smaller than min are replaced with min value.
Input values that are greater than max are replaced with max value.
Input values within the range
[min, max]
remain unchanged.
Let min_value and max_value be min and max, respectively. The mathematical formula of Clamp is as follows:
Attributes:
min
Description: min is the lower bound of values in the output.
Range of values: arbitrary floating-point number
Type:
float
Required: yes
max
Description: max is the upper bound of values in the output.
Range of values: arbitrary floating-point number
Type:
float
Required: yes
Inputs:
1: A tensor of type T and arbitrary shape. Required.
Outputs:
1: A tensor of type T with same shape as input tensor.
Types
T: any numeric type.
Note: In case of integral numeric type, ceil is used to convert min from
float
to T and floor is used to convert max fromfloat
to T.
