tf.sparse_segment_sqrt_n( data, indices, segment_ids, name=None, num_segments=None )
See the guide: Math > Segmentation
Computes the sum along sparse segments of a tensor divided by the sqrt(N).
N is the size of the segment being reduced.
Tensorwith data that will be assembled in the output.

data. Has same rank as
segment_ids: A 1-D
Tensorwith indices into the output
Tensor. Values should be sorted and can be repeated.
name: A name for the operation (optional).
num_segments: An optional int32 scalar. Indicates the size of the output
tensor of the shape as data, except for dimension 0 which has size
