tf.sparse_segment_sqrt_n

sparse_segment_sqrt_n(
    data,
    indices,
    segment_ids,
    name=None
)

Defined in tensorflow/python/ops/gen_math_ops.py.

See the guide: Math > Segmentation

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

N is the size of the segment being reduced.

Read the section on segmentation for an explanation of segments.

Args:

  • data: A Tensor. Must be one of the following types: float32, float64.
  • indices: A Tensor. Must be one of the following types: int32, int64. A 1-D tensor. Has same rank as segment_ids.
  • segment_ids: A Tensor of type int32. A 1-D tensor. Values should be sorted and can be repeated.
  • name: A name for the operation (optional).

Returns:

A Tensor. Has the same type as data. Has same shape as data, except for dimension 0 which has size k, the number of segments.
