Blockwise Subspace Identification for Active Noise Control [PDF]

open access: yes, 2000
In this paper, a subspace identification solution is provided for active noise control (ANC) problems. The solution is related to so-called block updating methods, where instead of updating the (feedforward) controller on a sample by sample base, it is ...

Robust auto-weighted multi-view subspace clustering with common subspace representation matrix. [PDF]

open access: yesPLoS ONE, 2017
In many computer vision and machine learning applications, the data sets distribute on certain low-dimensional subspaces. Subspace clustering is a powerful technology to find the underlying subspaces and cluster data points correctly.

On the Preconditioned Delayed Weighted Gradient Method

open access: yesTrends in Computational and Applied Mathematics, 2023
In this article a preconditioned version of the Delayed Weighted Gradient Method (DWGM) is presented and analyzed.  In addition to the convergence, some nice properties as  the A- orthogonality of the current transformed gradient with all the previous ...

Subspace Methods for Data Attack on State Estimation: A Data Driven Approach [PDF]

open access: yes, 2014
Data attacks on state estimation modify part of system measurements such that the tempered measurements cause incorrect system state estimates. Attack techniques proposed in the literature often require detailed knowledge of system parameters.

A nested Krylov subspace method to compute the sign function of large complex matrices [PDF]

open access: yes, 2011
We present an acceleration of the well-established Krylov-Ritz methods to compute the sign function of large complex matrices, as needed in lattice QCD simulations involving the overlap Dirac operator at both zero and nonzero baryon density.
