NthElement

public final class NthElement

Finds values of the `n`-th order statistic for the last dimension.

If the input is a vector (rank-1), finds the entries which is the nth-smallest value in the vector and outputs their values as scalar tensor.

For matrices (resp. higher rank input), computes the entries which is the nth-smallest value in each row (resp. vector along the last dimension). Thus,

values.shape = input.shape[:-1]

Constant Value: "NthElement"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static NthElement<T> create (Scope scope, Operand<T> input, Operand<TInt32> n, Options... options)

Factory method to create a class wrapping a new NthElement operation.

Parameters

scope	current scope
input	1-D or higher with last dimension at least `n+1`.
n	0-D. Position of sorted vector to select along the last dimension (along each row for matrices). Valid range of n is `[0, input.shape[:-1])`
options	carries optional attributes values

Returns

• a new instance of NthElement

public static NthElement.Options reverse (Boolean reverse)

Parameters

reverse	When set to True, find the nth-largest value in the vector and vice versa.

public Output<T> values ()

The `n`-th order statistic along each last dimensional slice.
