Class SparseReduceSumSparse<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.sparse.SparseReduceSumSparse<T>

Type Parameters:

T - data type for outputValues() output

All Implemented Interfaces:

Op

@Operator(group="sparse")
public final class SparseReduceSumSparse<T>
extends PrimitiveOp

Computes the sum of elements across dimensions of a SparseTensor.

This Op takes a SparseTensor and is the sparse counterpart to `tf.reduce_sum()`. In contrast to SparseReduceSum, this Op returns a SparseTensor.

Reduces `sp_input` along the dimensions given in `reduction_axes`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `reduction_axes`. If `keep_dims` is true, the reduced dimensions are retained with length 1.

If `reduction_axes` has no entries, all dimensions are reduced, and a tensor with a single element is returned. Additionally, the axes can be negative, which are interpreted according to the indexing rules in Python.

Factory method to create a class wrapping a new SparseReduceSumSparse operation.

Parameters:

scope - current scope

inputIndices - 2-D. `N x R` matrix with the indices of non-empty values in a SparseTensor, possibly not in canonical ordering.
