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

Sqrt(const std::shared_ptr<Node> &arg)

Constructs a square operation.

Parameters
• arg: Node that produces the input tensor.
