tensorflow:: ops:: SparseMatMul
#include <math_ops.h>
Multiply matrix "a" by matrix "b".
Summary
The inputs must be two-dimensional matrices and the inner dimension of "a" must match the outer dimension of "b". Both "a" and "b" must be Tensor
s not SparseTensor
s. This op is optimized for the case where at least one of "a" or "b" is sparse, in the sense that they have a large proportion of zero values. The breakeven for using this versus a dense matrix multiply on one platform was 30% zero values in the sparse matrix.
The gradient computation of this operation will only take advantage of sparsity in the input gradient when that gradient comes from a Relu.
Args:
- scope: A Scope object
Returns:
Output
: The product tensor.
