tensorflow::ops::UnsortedSegmentMax

#include <math_ops.h>

Computes the maximum along segments of a tensor.

Summary

Read the section on segmentation for an explanation of segments.

This operator is similar to the unsorted segment sum operator found (here). Instead of computing the sum over segments, it computes the maximum such that:

\(output_i = data_j\) where max is over j such that segment_ids[j] == i.

If the maximum is empty for a given segment ID i, it outputs the smallest possible value for the specific numeric type, output[i] = numeric_limits::lowest().

Arguments:

• scope: A Scope object
• segment_ids: A 1-D tensor whose rank is equal to the rank of data's first dimension.

Returns:

• Output: Has same shape as data, except for dimension 0 which has size num_segments.
