Various embodiments relating to encoding a sparse matrix into a data structure format that may be efficiently processed via parallel processing of a computing system are provided. In one embodiment, a sparse matrix may be received. A set of designated rows of the sparse matrix may be traversed ...
Algorithms for symmetric matrix square and inverse Cholesky decomposition within the hierarchic framework are also described. The presented data structure is general; in addition to its use in Hartree-Fock/Kohn-Sham calculations, it may also be used in other research areas where matrices with similar...
A sparse matrix normalization device 10 is provided with: a calculation unit 11 which performs, for each column of a target matrix to be normalized, a calculation process to calculate the average and standard deviation of the value of each component of the column; a first dividing unit 12 whi...
If you want to process speech signals, you need to change the mixing matrix estimation method. Dear Pro. Ishwarya Venkatesh, the corresponding paper has been submitted to shock and vibration. Due to SCA based on instaneous mixing model, so it is only able to process sensor data withou...

(1) We improved the data locality and indirect memory access speed by blocking, using a multicolor reordering method to develop the fine-grained parallelism of the Gauss–Seidel algorithm, and dividing the data finely according to the memory structure of the Matrix-DSP. (2) In terms of the ...
The confusion matrix is used to evaluate the classification performance of the dictionary learning algorithms on the testing database. Three main metrics are calculated from Table 1. Table 1. Confusion matrix for TSA classification. The accuracy metric defines the ability of learned dictionaries for...

The remaining matrix is factored by a dense LU procedure. Raising the density tolerance towards 1.0 may give slightly sparser LU factors, with a slight increase in factorization time. The singularity tolerance r2 helps guard against ill-conditioned basis matrices. When the basis is refactorized, ...
