Add sparse tensors of the same shape by using tf.sparse.add. of dense dimensions. It is possible to explicitly include zero values in the values of a COO sparse matrix, but these "explicit zeros" are generally not included when referring to nonzero values in a sparse tensor. subtracted by the number before it denotes the number of Content Discovery initiative April 13 update: Related questions using a Review our technical responses for the 2023 Developer Survey. mat1 (Tensor) the first sparse matrix to be multiplied, mat2 (Tensor) the second matrix to be multiplied, which could be sparse or dense. values and indices tensor(s) must match.
