Tanh¶
Versioned name : Tanh-1
Category : Arithmetic unary
Short description : Tanh performs element-wise hyperbolic tangent (tanh) operation with given tensor.
Detailed description
For each element from the input tensor calculates corresponding element in the output tensor with the following formula:
\[tanh ( x ) = \frac{2}{1+e^{-2x}} - 1 = 2sigmoid(2x) - 1\]
For integer element type the result is rounded (half up) to the nearest integer value.
Attributes : Tanh operation has no attributes.
Inputs :
1 : A tensor of type T and arbitrary shape. Required.
Outputs :
1 : The result of element-wise Tanh operation. A tensor of type T and the same shape as input tensor. Types
T : any numeric type.
