Computes the mean along segments of a tensor.


  • tf.compat.v1.math.unsorted_segment_mean
  • tf.compat.v1.unsorted_segment_mean
  • tf.compat.v2.math.unsorted_segment_mean

Read the section on segmentation for an explanation of segments.

This operator is similar to the unsorted segment sum operator found here免费成长做爱直播有哪些. Instead of computing the sum over segments, it computes the mean of all entries belonging to a segment such that:

\(outputi = 1/N_i \sum{j...} data[j...]\) where the sum is over tuples j... such that segment_ids[j...] == i with \N_i\ being the number of occurrences of id \i\.

If there is no entry for a given segment ID i免费成长做爱直播有哪些, it outputs 0.

If the given segment ID i免费成长做爱直播有哪些 is negative, the value is dropped and will not be added to the sum of the segment.


  • data: A Tensor with floating point or complex dtype.
  • segment_ids: An integer tensor whose shape is a prefix of data.shape.
  • num_segments: An integer scalar Tensor. The number of distinct segment IDs.
  • name: A name for the operation (optional).


A Tensor. Has same shape as data, except for the first segment_ids.rank dimensions, which are replaced with a single dimension which has size num_segments.
