Sign¶
Versioned name : Sign-1
Category : Arithmetic unary
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:
\[a_{i} = sign(a_{i})\]
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">

<port id="0">
<dim>256</dim>
<dim>56</dim>
</port>
</input>
<output>
<port id="1">
<dim>256</dim>
<dim>56</dim>
</port>
</output>
