Very Large-Scale Singular Value Decomposition Using Tensor Train Networks [PDF]

open access: yes, 2014
We propose new algorithms for singular value decomposition (SVD) of very large-scale matrices based on a low-rank tensor approximation technique called the tensor train (TT) format. The proposed algorithms can compute several dominant singular values and

Macroscopic fluctuations emerge in balanced networks with incomplete recurrent alignment

open access: yesPhysical Review Research, 2021
Networks of strongly coupled neurons with random connectivity exhibit chaotic, asynchronous fluctuations. In a previous study, we showed that when endowed with an additional component of low-rank connectivity consisting of the outer product of orthogonal

Extreme Singular Values of Random Time-Frequency Structured Matrices [PDF]

open access: yes, 2019
In this paper, we investigate extreme singular values of the analysis matrix of a Gabor frame $(g, \Lambda)$ with a random window $g$. Columns of such matrices are time and frequency shifts of $g$, and $\Lambda\subset \mathbb{Z}_M\times\mathbb{Z}_M$ is ...

Robust control of ill-conditioned plants: high-purity distillation [PDF]

open access: yes, 1988
Using a high-purity distillation column as an example, the physical reason for the poor conditioning and its implications on control system design and performance are explained.

Non-Markovian Decay and Lasing Condition in an Optical Microcavity Coupled to a Structured Reservoir [PDF]

open access: yes, 2006
The decay dynamics of the classical electromagnetic field in a leaky optical resonator supporting a single mode coupled to a structured continuum of modes (reservoir) is theoretically investigated, and the issue of threshold condition for lasing in ...

svt: Singular Value Thresholding in MATLAB

open access: yesJournal of Statistical Software, 2017
Many statistical learning methods such as matrix completion, matrix regression, and multiple response regression estimate a matrix of parameters. The nuclear norm regularization is frequently employed to achieve shrinkage and low rank solutions.

Finding structure with randomness: Probabilistic algorithms for constructing approximate matrix decompositions [PDF]

open access: yes, 2010
Low-rank matrix approximations, such as the truncated singular value decomposition and the rank-revealing QR decomposition, play a central role in data analysis and scientific computing.

Observability and Synchronization of Neuron Models [PDF]

open access: yes, 2017
Observability is the property that enables to distinguish two different locations in $n$-dimensional state space from a reduced number of measured variables, usually just one.
