cntk:argmin

cntk:argmin(
   $operand as cntk:variable,
   $axis as cntk:axis,
   [$name as xs:string]
) as cntk:function

Summary

Computes the argmin of the input tensor’s elements across the specified axis. If no axis is specified, it will return the flatten index of the smallest element in tensor x.

Parameters
$operand Any Function that outputs a tensor.
$axis Axis along which the reduction will be performed.
$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 $input-variable2 := cntk:input-variable(cntk:shape((3)), "float",
    fn:false(), fn:false(), "feature")
  return cntk:argmin($input-variable2, cntk:axis(0), "@<H54c")
  => cntk:function(Composite ReduceElements (Input(Name(feature), Shape([3]),
  Dynamic Axes([Sequence Axis(Default Dynamic Axis), Batch Axis(Default Batch
  Axis)]))))
