tf.compat.v1.sparse_segment_sqrt_n

Computes the sum along sparse segments of a tensor divided by the sqrt(N).

tf.compat.v1.sparse_segment_sqrt_n(
    data, indices, segment_ids, name=None, num_segments=None
)

N is the size of the segment being reduced.

data A Tensor with data that will be assembled in the output.
indices A 1-D Tensor with indices into data. Has same rank as segment_ids.
segment_ids A 1-D Tensor with 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.

A tensor of the shape as data, except for dimension 0 which has size k, the number of segments specified via num_segments or inferred for the last element in segments_ids.
