tensorflow::ops::UnsortedSegmentMax
tensorflow::ops::UnsortedSegmentMax
#include <math_ops.h>
Computes the Max along segments of a tensor.
Summary
Read$math_ops::segmentation$the section on segmentation} for an explanation of segments.
This operator is similar to the unsorted segment sum operator. 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 specific numeric type, output[i] = numeric_limits
.
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 sizenum_segments
.
