cntk:reduce-log-sum(
   $x as cntk:variable,
   $axis as cntk:axis,
   [$name as xs:string]
) as cntk:function

Summary

Create an instance of the CNTK built-in LogSum reduction operation on specified tensor input operand along the specified axis

Parameters
$x Input tensor.
$axis Axis along which the reduction will be performed.
$name The name of the function instance in the network.

Example

  let $input-variable := cntk:input-variable(cntk:shape((3)), "float", fn:false(),
    fn:false(), "feature")
  return cntk:reduce-log-sum($input-variable, cntk:axis(0), ">5KpKUx")
  => cntk:function(Composite ReduceElements (Input(Name(feature), Shape([3]),
  Dynamic Axes([Sequence Axis(Default Dynamic Axis), Batch Axis(Default Batch Axis)]))))
