稀疏矩阵:若数值为零的元素数目远远多于非0元素的数目时,则称该矩阵为稀疏矩阵 密集(稠密)矩阵:若非0元素数目占大多数时,则称该矩阵为密集矩阵 稀疏性:可以用一个得分来量化,就是矩阵种零值的个数除以矩阵种元素的总数。 比如:一个 3×6 的矩阵,共有18各元素,13个零值时,这个矩阵的得分是0.722或72%。 编辑于 2023-04-16 01:16・新疆 稀疏
稀疏矩阵Sparse Matrix是一种特殊的矩阵,其特点在于矩阵中数值为0的元素数目远远多于非0元素的数目,并且这些非0元素的分布没有规律。 简单地说,稀疏矩阵Sparse Matrix的行数和列数与其稀疏性没有直接的关系。稀疏矩阵Sparse Matrix的定义主要是基于矩阵Matrix中非零元素的数量与矩阵元素总数的比例。当这个比例小于或等于...

The results show that the proposed sparse matrix multipliers can outperform dense multipliers when sparsity levels are higher than 70% and the improvements are more evident when higher precision arithmetic or structural pruning is used. Additionally, sparsity levels as high as 99% can maintain the ...

Consider the parallelization of sparse matrix dense matrix multiplication (SpMM) of the formY=AX,whereAis ann×nsparse matrix, andXandYaren×sdense matrices. Assume thatAis permuted into aK-way block structure of the formABL=[C1⋯CK]=[R1⋮RK]=[A11⋯A1K⋮⋱⋮AK1⋯AKK],for row...
Hi, Have a quick question to ask, I need to do A x B where A is a sparse matrix stored in CSR format, B is a symmetric dense matrix. Now I am using
I have a problem where I need to multiply a dense matrix by a sparse matrix. The function "mkl_?csrmm" asks for the first matrix to be sparse and the second to be dense. But my case is opposite. Problem: C = A * B + C , where A is dense and B is...
