In-depth solution and explanation for LeetCode 311. Sparse Matrix Multiplication in Python, Java, C++ and more. Intuitions, example walk through, and complexity analysis. Better than official …

We present a new algorithm that multiplies A and B using O(m0.7n1 .2 n2 +o(1)) algebraic operations (i.e., multiplications, additions and subtractions) over. The na ̈ıve matrix …

SpGEMM is a special case of general matrix multiplication (GEMM) when two input matrices are sparse matrices.

Right now my sparse matrices are basically implemented a wrapped std::map< std::pair<int, int>, double> which stores the data, if any. This transforms the multiplication of a matrix with from …

Generalized sparse matrix-matrix multiplication (or SpGEMM) is a key primitive for many high performance graph algorithms as well as for some linear solvers, such as algebraic multi-grid.

To address this problem, this paper proposes an efficient sparse matrix multiplication accelerator architecture, SpArch, which jointly optimizes the data locality for both input and output matrices.

We implement two novel algorithms for sparse-matrix dense-matrix multiplication (SpMM) on the GPU. Our algorithms expect the sparse input in the popular compressed-sparse-row (CSR) …

A common operation on sparse matrices is to multiply them by a dense vector. In such an operation, the result is the dot-product of each sparse row of the matrix with the dense vector. …

the new algorithm is also faster than the best known matrix multiplication algorithm for dense matrices which uses O ( n 2 : 38 ) algebraic operations. The new algorithm is obtained using a …
