tensorflow:: ops:: TopK

#include <nn_ops.h>

Finds values and indices of the k largest elements for the last dimension.

Summary

If the input is a vector (rank-1), finds the k largest entries in the vector and outputs their values and indices as vectors. Thus values[j] is the j -th largest entry in input , and its index is indices[j] .

For matrices (resp. higher rank input), computes the top k entries in each row (resp. vector along the last dimension). Thus, 

values.shape = indices.shape = input.shape[:-1] + [k]

If two elements are equal, the lower-index element appears first.

Args:

  • scope: A Scope object
  • input: 1-D or higher with last dimension at least k .
  • k: 0-D. Number of top elements to look for along the last dimension (along each row for matrices).

Optional attributes (see Attrs ):

  • sorted: If true the resulting k elements will be sorted by the values in descending order.

Returns:

  • Output values: The k largest elements along each last dimensional slice.
  • Output indices: The indices of values within the last dimension of input .
