cntk:ndcgat1

cntk:ndcgat1(
   $prediction as cntk:variable,
   $gains as cntk:variable,
   $group-id as cntk:variable,
   [$name as xs:string]
) as cntk:function

Summary

Create an instance of the CNTK built-in operation for evaluating the NDCG at 1 metric

Parameters
$prediction
$gains
$group-id
$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 $input-variable2 := cntk:input-variable(cntk:shape((3)), "float",
    fn:false(), fn:false(), "feature")
  return cntk:ndcgat1($input-variable1, $input-variable2, $input-variable2)
  => cntk:function(Composite LambdaRank (Input(Name(feature), Shape([3]),
  Dynamic Axes([Sequence Axis(Default Dynamic Axis), Batch Axis(Default Batch
  Axis)])), Input(Name(feature), Shape([3]), Dynamic Axes([Sequence Axis(Default
  Dynamic Axis), Batch Axis(Default Batch Axis)]))))
