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 System Identification of the Kalman Filter [PDF]

open access: yesModeling, Identification and Control, 2003
Some proofs concerning a subspace identification algorithm are presented. It is proved that the Kalman filter gain and the noise innovations process can be identified directly from known input and output data without explicitly solving the Riccati ...

Multiway Filtering Based on Fourth-Order Cumulants

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose a new multiway filtering based on fourth-order cumulants for the denoising of noisy data tensor with correlated Gaussian noise. The classical multiway filtering is based on the TUCKALS3 algorithm that computes a lower-rank tensor ...

Cone-restricted subspace methods [PDF]

open access: yes2008 19th International Conference on Pattern Recognition, 2008
In pattern recognition, feature vectors are occasionally subject to non-negative constraints. This characteristic can be expressed by a cone in feature vector space. In this paper, we propose cone-restricted subspace methods. The proposed methods admit the scaling and additivity of vectors as well as ordinary subspace methods; in addition, vectors can ...

Coherent Control of Nitrogen Nuclear Spins via the VB−${\rm V}_B^-$‐Center in Hexagonal Boron Nitride

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates coherent control of 15N nuclear spins coupled to VB−${\text{V}}_{\text{B}}^{-}$ centers in isotope‐enriched hexagonal boron nitride. Selective addressing via spin‐state mixing enables Rabi driving, quantum gates, and coherence times exceeding 10 μs$\umu{\rm s}$.

Imaging of Biphoton States: Fundamentals and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...
