UnsortedSegmentJoin

public final class UnsortedSegmentJoin

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 Output<String> output ()

public static UnsortedSegmentJoin.Options separator (String separator)

Parameters
separator The separator to use when joining.
