Tanh

Tanh  // Elementwise hyperbolic tangent operation.

Description

Produce a tensor with the same shape and element typye as arg, where the value at each coordinate of output is the hyperbolic tangent of the value of arg at the same coordinate.

Inputs

Name Element Type Shape
arg Any Any

Outputs

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \tanh(\mathtt{arg}_{i_0, \ldots, i_{n-1}})\]

Backprop

\[\overline{\mathtt{arg}} \leftarrow \Delta\ (1 - \mathtt{output}^2)\]

C++ Interface

class Tanh : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise hyperbolic tangent operation.

Public Functions

const NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.

Tanh(const Output<Node> &arg)

Constructs a hyperbolic tangent operation.

Parameters
  • arg: Node that produces the input tensor.
