tensorflow:: ops:: UnsortedSegmentJoin

#include <string_ops.h>

Joins the elements of inputs based on segment_ids .

Summary

Computes the string join along segments of a tensor. Given segment_ids with rank N and data with rank N+M : 

`output[i, k1...kM] = strings.join([data[j1...jN, k1...kM])`

where the join is over all [j1...jN] such that segment_ids[j1...jN] = i. Strings are joined in row-major order.

For example: 

inputs = [['Y', 'q', 'c'], ['Y', '6', '6'], ['p', 'G', 'a']]
output_array = string_ops.unsorted_segment_join(inputs=inputs,
                                                segment_ids=[1, 0, 1],
                                                num_segments=2,
                                                separator=':'))
# output_array ==> [['Y', '6', '6'], ['Y:p', 'q:G', 'c:a']]

inputs = ['this', 'is', 'a', 'test']
output_array = string_ops.unsorted_segment_join(inputs=inputs,
                                                segment_ids=[0, 0, 0, 0],
                                                num_segments=1,
                                                separator=':'))
# output_array ==> ['this:is:a:test']

Args:

  • scope: A Scope object
  • inputs: The input to be joined.
  • segment_ids: A tensor whose shape is a prefix of data.shape. Negative segment ids are not supported.
  • num_segments: A scalar.

Optional attributes (see Attrs ):

  • separator: The separator to use when joining.
