UnsortedSegmentSum

tensorflow C++ API

tensorflow::ops::SegmentMax

Computes the sum along segments of a tensor.

Summary

Read the section on segmentation for an explanation of segments.

Computes a tensor such that(output[i] = sum_{j...} data[j...]where the sum is over tuplesj...such thatsegment_ids[j...] == i. UnlikeSegmentSum,segment_idsneed not be sorted and need not cover all values in the full range of valid values.

If the sum is empty for a given segment IDi,output[i] = 0.

num_segmentsshould equal the number of distinct segment IDs.

Arguments:

• scope: A Scope object
• segment_ids: A tensor whose shape is a prefix ofdata.shape.

Returns:

• Output: Has same shape as data, except for the firstsegment_ids.rankdimensions, which are replaced with a single dimension which has sizenum_segments.

Constructor

• UnsortedSegmentSum(const ::tensorflow::Scope & scope, ::tensorflow::Input data, ::tensorflow::Input segment_ids, ::tensorflow::Input num_segments)

Public attributes

• tensorflow::Output output.

Argument:

• Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.).
• Input data:connect Input node.
• Input segment_ids:connect Input node.
• Input num_segments : connect Input node.

Return:

• Output output: Output object of UnsortedSegmentSum class object.

Result:

• std::vector(Tensor) product_result : Returned object of executed result by calling session.
