cntk:sum

cntk:sum(
   $operands as cntk:variable,
   [$name as xs:string]
) as cntk:function

Summary

Create a new Function instance that computes element-wise sum of input tensors.

Parameters
$operands List of functions.
$name The name of the function instance in the network.

Example

  let $input-variable1 := cntk:input-variable(cntk:shape((3)), "float",
    fn:false(), fn:false(), "feature")
  let $input-variable2 := cntk:input-variable(cntk:shape((3)), "float",
    fn:false(), fn:false(), "feature")
  return cntk:sum($input-variable2, "X#aWjz")
  => cntk:function(Composite Sum (Input(Name(feature), Shape([3]),
  Dynamic Axes([Sequence Axis(Default Dynamic Axis), Batch Axis(Default Batch Axis)]))))
