Fusing Local and Global Information for One-Step Multi-View Subspace Clustering

open access: yesApplied Sciences, 2022
Multi-view subspace clustering has drawn significant attention in the pattern recognition and machine learning research community. However, most of the existing multi-view subspace clustering methods are still limited in two aspects.

On the topology of free paratopological groups

open access: yes, 2012
The result often known as Joiner's lemma is fundamental in understanding the topology of the free topological group $F(X)$ on a Tychonoff space$X$. In this paper, an analogue of Joiner's lemma for the free paratopological group $\FP(X)$ on a $T_1$ space $

Direct position tracking method for non-circular signals with distributed passive arrays via first-order approximation

open access: yesETRI Journal
In this study, a direct position tracking method for non-circular (NC) signals using distributed passive arrays is proposed. First, we calculate the initial positions of sources using a direct position determination (DPD) approach; next, we transform the

Optimizing Tree-Based Contrast Subspace Mining Using Genetic Algorithm

open access: yesInternational Journal of Computational Intelligence Systems, 2022
Mining contrast subspace is a task of finding contrast subspace where a given query object is most similar to a target class but dissimilar to non-target class in a multidimensional data set.

Tensor products of subspace lattices and rank one density

open access: yes, 2012
We show that, if $M$ is a subspace lattice with the property that the rank one subspace of its operator algebra is weak* dense, $L$ is a commutative subspace lattice and $P$ is the lattice of all projections on a separable infinite dimensional Hilbert ...

Explicit subspace designs [PDF]

open access: yesCombinatorica, 2013
An \((s,A)\) subspace design is a set of linear subspaces \(H_1, \dots, H_M\) of \(F_q^m\) such that for every \(s\)-dimensional subspace \(W\) of \(F_q^m\) at most \(A\) of the \(H_i\) intersect \(W\) non-trivially. In this paper, the authors refine the construction of the first author and \textit{C.

On Subspace-ergodic Operators

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
In this paper, we define subspace-ergodic operators and give examples of these operators. We show that by any given separable infinite-dimensional Banach space, subspace-ergodic operators can be constructed.

MOON: A Subspace-Based Multi-Branch Network for Object Detection in Remotely Sensed Images

open access: yesRemote Sensing, 2023
The effectiveness of training-based object detection heavily depends on the amount of sample data. But in the field of remote sensing, the amount of sample data is difficult to meet the needs of network training due to the non-cooperative imaging modes ...
