Joins the elements of `inputs` based on `segment_ids`.
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']

Inherited Methods
Public Methods
public Output <String> asOutput ()
Returns the symbolic handle of a 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 UnsortedSegmentJoin create ( Scope scope, Operand <String> inputs, Operand <T> segmentIds, Operand <U> numSegments, Options... options)
Factory method to create a class wrapping a new UnsortedSegmentJoin operation.
Parameters
scope | current scope |
---|---|
inputs | The input to be joined. |
segmentIds | A tensor whose shape is a prefix of data.shape. Negative segment ids are not supported. |
numSegments | A scalar. |
options | carries optional attributes values |
Returns
- a new instance of UnsortedSegmentJoin
public static UnsortedSegmentJoin.Options separator (String separator)
Parameters
separator | The separator to use when joining. |
