cntk.reduceLogSumOnAxes

cntk.reduceLogSumOnAxes(
   $x as cntk.variable,
   $axes as cntk.axis[],
   [$keep-dims as Boolean],
   [$name as 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.
$axes Axes along which the reduction will be performed.
$keep-dims Whether to keep dimensions.
$name The name of the function instance in the network.

Example

  var inputVariable = cntk.inputVariable(cntk.shape([3]), "float", fn.false(),
    fn.false(), "feature")
  cntk.reduceLogSum(inputVariable, 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)]))))
