Sqrt

Sqrt  //  Elementwise square root operation

Description

Produces a tensor of the same element type and shape as arg, where the value at each coordinate of output is the square root of the value at the corresponding coordinate of arg.

Inputs

Name Element Type Shape
arg Any Any

Outputs

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

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

Backprop

\[\overline{\mathtt{arg}} \leftarrow \frac{\Delta}{2\cdot \mathtt{output}}\]

C++ Interface

class Sqrt : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise square root operation.

Inputs

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.

Sqrt(const Output<Node> &arg)

Constructs a square operation.

Parameters
  • arg: Node that produces the input tensor.
