Tanh
Versioned name: Tanh-1
Category: Arithmetic function
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: \f[ tanh ( x ) = \frac{2}{1+e^{-2x}} - 1 = 2sigmoid(2x) - 1 \f]
- 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.
