SegmentSum

tensorflow C++ API

tensorflow::ops::SegmentSum

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 = data_j where sum is overjsuch thatsegment_ids[j] == i.

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

Arguments:

• scope: A Scope object
• segment_ids: A 1-D tensor whose rank is equal to the rank of data's first dimension. Values should be sorted and can be repeated.

Returns:

• Output: Has same shape as data, except for dimension 0 which has sizek, the number of segments.

Constructor

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

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.

Return:

• Output output: Output object of SegmentSum class object.

Result:

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