An algorithm was proposed, using sparse matrix as the storage structure of the data. To prevent the critical path from being lost, the queue method was adopted for the operation. Compared with the classical algorithm, this algorithm is simple, with close asymptotic time complexity (O (n e~2...
Fast Sparse Matrix-Vector Multiplication on GPUs: Implications for Graph Mining Scaling up the sparse matrix-vector multiplication kernel on modern Graphics Processing Units (GPU) has been at the heart of numerous studies in both acade... X Yang,S Parthasarathy,P Sadayappan - 《Proceedings of ...
A new algorithm for reducing the bandwidth and profile of a sparse matrix is described. Extensive testing on finite element matrices indicates that the algorithm typically produces bandwidth and profile which are comparable to those of the commonly-used reverse Cuthill-McKee algorithm, yet requires sig...

We describe an efficient implementation of an algorithm for computing selected elements of a general sparse symmetric matrix A that can be decomposed as A = LDLT where L is lower triangular and D is diagonal. Our implementation, which is called SelInv, is built on top of an efficient supermo...

When the matrix is sparse this method works fine because sparse matrices take less time to compute. It is not practically possible as it is computation and theoretical approach only. It takes more space for storing sub matrices. There is less chance of accuracy. Chat on Discord ...
(CNN) uses a sequence of 2 operations,convolutionand pooling, repeatedly on theinput data. CNN are a subset ofFFNNwith a special structure, including sparse connectivity between layers and shared weights, which have surpassed conventional methods in modelling the sequence specificity of DNA-protein ...
