Erf

Versioned name: Erf-1

Category: Arithmetic unary

Short description: Erf performs element-wise Gauss error function (erf) on a given input tensor.

Detailed Description

Erf performs element-wise erf operation on a given input tensor, based on the following mathematical formula:

\f[ erf(x) = \pi^{-1} \int_{-x}^{x} e^{-t^2} dt \f]

Attributes: Erf operation has no attributes.

Inputs

• 1: A tensor of type T and arbitrary shape. Required.

Outputs

• 1: The result of element-wise Erf function applied to the input tensor. A tensor of type T and the same shape as the input tensor.

Types

• T: any supported numeric type.

Example

<layer ... type="Erf">
    <input>
        <port id="0">
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </input>
    <output>
        <port id="1">
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </output>
</layer>
