Sentence examples for sparsity pattern from inspiring English sources

This allows us to investigate the impact of the preconditioner's sparsity pattern with respect to the computational performance.

In fact, the resulting stiffness matrix has a similar sparsity pattern as that of the statically condensed continuous Galerkin (CG) method.

The method applied overcomes these difficulties by imposing a multi-level substructuring procedure, based on the sparsity pattern of the stiffness matrix.

Using DAEPACK generated code, analytical derivative calculations, sparsity pattern information, and hidden discontinuity information can be obtained for the models of interest.

Matrix matrix multiplications are expensive, may lead to loss of accuracy and destroy the sparsity pattern present in the original system.

We focus on an hybrid acceleration of the implicitly restarted Arnoldi method which targets large non-symmetric problems with irregular sparsity pattern.

ℓ2,1-norm is based on the postulate that the features from the same class will have a common sparsity pattern in the feature space.

Since the assumption of common sparsity pattern is very restrictive, we are more interested in signal ensemble containing both common and innovation components.

This is true not only for the dropping based on magnitude of entries but it also applies to algorithms that use a prescribed sparsity pattern.

This new approach allows the construction of local conditions that (a) are independent of the frequency regime, (b) preserve the sparsity pattern of the finite element discretization, and (c) are applicable to arbitrarily shaped convex artificial boundaries.

Further, by exploiting the sparsity pattern exhibited by the problem, we show that the original POP can be equivalently reformulated as an SDP problem with a rank-1 constraint.
