Softsign (input) => (output)
{
   One = Constant <value: tensor = float {1}> ()
   OneCast = CastLike (One, input)
   AbsInput = Abs (input)
   OneAddAbsInput = Add (OneCast, AbsInput)
   output = Div (input, OneAddAbsInput)
}

Inputs#

  • input (heterogeneous) - T:

    Input tensor

Outputs#

  • output (heterogeneous) - T:

    The softsign (x/(1+|x|)) values of the input tensor computed element-wise

Type Constraints#

  • T in ( tensor(double), tensor(float), tensor(float16) ):

    Constrain input and output types to float tensors.
