Sign

Versioned name: Sign-1

Category: Arithmetic unary operation

Short description: Sign performs element-wise sign operation on a given input tensor.

Detailed description: Sign performs element-wise sign operation on a given input tensor, based on the following mathematical formula:

\f[ a_{i} = sign(a_{i}) \f]

Attributes: Sign operation has no attributes.

Inputs

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

Outputs

  • 1: The result of element-wise Sign operation. A tensor of type T with mapped elements of the input tensor to -1 (if it is negative), 0 (if it is zero), or 1 (if it is positive).

Types

  • T: any numeric type.

Example

<layer ... type="Sign">
    <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>
