tf.raw_ops.NthElement

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

tf.raw_ops.NthElement(
    input, n, reverse=False, name=None
)

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]

Args:

  • input: A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, int64, bfloat16, uint16, half, uint32, uint64. 1-D or higher with last dimension at least n+1.
  • n: A Tensor of type int32. 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])
  • reverse: An optional bool. Defaults to False. When set to True, find the nth-largest value in the vector and vice versa.
  • name: A name for the operation (optional).

Returns:

A Tensor. Has the same type as input.
