Computes the sum along sparse segments of a tensor divided by the sqrt(N).
tf.sparse.segment_sqrt_n( data, indices, segment_ids, name=None, num_segments=None )
N
is the size of the segment being reduced.
Args | |
---|---|
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 . |
Returns | |
---|---|
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 . |
