Web1. dec 2024 · While traditional sparsity promoting algorithms destabilize the delayed system in most cases, ours preserve stability. In the second half of the paper, we extend these algorithms to a multiple user scenario and assign a fair number of communication links to each user to reduce the variance of their H 2 performances. Both problems are complex ...

Lixin Shen, Bruce W. Suter, Erin E. Tripp. Motivated by the minimax concave penalty based variable selection in high-dimensional linear regression, we introduce a simple scheme to construct structured semiconvex sparsity promoting functions from convex sparsity promoting functions and …
Web29. mar 2024 · Bayesian hierarchical models have been demonstrated to provide efficient algorithms for finding sparse solutions to ill-posed inverse problems. The models comprise typically a conditionally Gaussian prior model for the unknown, augmented by a hyperprior model for the variances. A widely used choice for the hyperprior is a member of the family … Web13. apr 2024 · The scheme removes redundant filters and reduces the impact that these filters have on the overall learning of the network by promoting sparsity. In addition, in contrast to previous works that make use of pseudo-norm-based sparsity-inducing constraints, the framework that we have developed includes a sparse scheme that is …
Webdue to inherent linear nature, sparsity-promoting DMD (Jovanovic, et al., 2014) cannot provide accurate representation for Koopman mode decomposition in a transient regime. due to lack of truncation on nonlinearly evolving modes, spDMD can end up with spurious unstable Koopman modes for stable flows. Web29. aug 2024 · The SLMS is an adaptive filtering algorithm that takes advantage of the sparsity of the underlying system response-which is present in many HA DSP applications-for improved convergence behavior...
