Anchor-based multi-view clustering has garnered much attention for its effectiveness in handling massive datasets. However, current methods either fail to consider intra-view similarity or require (\mathcal {O}(N^{3})) for exploring intra-view similarity, making efficient large-scale multi-view clustering difficult. This paper introduces a novel tensor low-frequency component (TLFC) operator, wh...Show More
On 3D imaging, light field cameras are typically single-shot. However, they often suffer from low spatial resolution and limited depth accuracy. In this paper, by employing an optical projector to project a group of high-frequency phase-shifted sinusoid patterns, we propose a phase-guided light field algorithm to significantly improve both the spatial and depth resolutions for off-the-shelf light ...Show More
WiFi systems offer enormous potential for device-free human intrusion detection. Current methods often require routers to be deployed in multiple adjacent rooms on the same floor, which is redundant and costly. To solve this, we introduce the first work on intrusion detection in the crossing-floor scenario via WiFi. Routers on different floors are utilized without major modifications to the existi...Show More
Alzheimer’s disease (AD) is an incurable neurodegenerative disease that involves structural changes in the brain. Early diagnosis of AD helps provide timely treatment and delay its progressive process. Many studies have been conducted based on brain images to detect AD. However, these works are mostly designed based on multi-modal brain data. The existing methods on uni-modal data, e.g., diffusion...Show More
Generative Adversarial Networks (GANs) can map a latent vector sampled from a random distribution to a photorealistic image. Previous methods attempt to leverage the semantic features embedded in the latent space to enable local editing but encounter challenges in accurately disentangling these features. In this paper, we analyze the redundant characteristics inherent in the deconvolution mechanis...Show More
Robust tensor principal component analysis (RTPCA) based on tensor singular value decomposition (t-SVD) separates the low-rank component and the sparse component from the multiway data. For streaming data, online RTPCA (ORTPCA) processes tensor data sequentially, where the low-rank component is updated based on the latest estimation and the newly arrived sample. It enhances both computation and st...Show More
Despite the significant progress made by deep clustering models in high-dimensional data processing, they remain vulnerable to adversarial examples. However, research on adversarial attacks against deep clustering algorithms appears to be relatively underexplored. To fill this gap, we propose a query-efficient black-box attack on deep clustering models, which leverages the transferability between ...Show More
Anchor-based large-scale multi-view clustering has attracted considerable attention for its effectiveness in handling massive datasets. However, current methods mainly seek the consensus embedding feature for clustering by exploring global correlations between anchor graphs or projection matrices. In this paper, we propose a simple yet efficient scalable multi-view tensor clustering (S2MVTC) appro...Show More
The amygdala plays a vital role in emotional processing and exhibits structural diversity that necessitates fine-scale parcellation for a comprehensive understanding of its anatomico-functional correlations. Diffusion MRI tractography is an advanced imaging technique that can estimate the brain’s white matter structural connectivity to potentially reveal the topography of the amygdala for studying...Show More
Versatile video coding (VVC) adopts a hierarchical coding structure to exploit the inherent temporal rate-distortion (R-D) dependency resulting from inter-prediction, but the scheme does not support at the coding tree unit (CTU)-level. In this paper, we present a CTU-level Lagrange multiplier and quantization parameter (QP) adaptation method in VVC random access (RA) configuration, aimed at enhanc...Show More
Epilepsy is a common neurological disease that seriously affects the patient’s life quality. Electroencephalogram (EEG) is an important modality for epilepsy diagnosis and treatment. Here, we propose a tensor-based method using EEG, which can detect patients with seizures and identify them. In this method, we transform EEG signals into high-order tensors and design a regularized O-minus tensor net...Show More
An image line segment is a fundamental low-level visual feature that delineates straight, slender, and uninterrupted portions of objects and scenarios within images. Detection and description of line segments lay the basis for numerous vision tasks. Although many studies have aimed to detect and describe line segments, a comprehensive review is lacking, obstructing their progress. This study fills...Show More
In recent years, fusing high spatial resolution multispectral images (HR-MSIs) and low spatial resolution hyperspectral images (LR-HSIs) has become a widely used approach for hyperspectral image super-resolution (HSI-SR). Various unsupervised HSI-SR methods based on deep image prior (DIP) have gained wide popularity thanks to no pre-training requirement. However, DIP-based methods often demonstrat...Show More
Multi-view subspace clustering employs learned self-representation from multiple tensor decompositions to exploit the low-rank information. However, the data structures embedded with self-representation tensors may vary in different multi-view datasets. Therefore, a pre-defined decomposition may not fully exploit low-rank information from various data, resulting in sub-optimal multi-view clusterin...Show More
Dysphagia is a prevalent symptom in numerous neurological disorders among older adults. Current dysphagia diagnostic systems either involve invasive procedures or necessitate the ingestion of liquids. Some researchers have devised automatic dysphagia detection methods based on vowels that are easy to collect and sensitive to vocal cord states. These methods extract features from each vowel separat...Show More
Phase retrieval seeks to reconstruct a series of image sequences from measurements that only capture their magnitudes. Current approaches either flatten and stack the image sequences, disregarding their multidimensional structural information, or fail to account for errors within the sensing vectors/tensors. To address these two issues simultaneously, we propose a unified framework for the phase r...Show More
Objective: Alzheimer's disease (AD) is a slowly progressive neurodegenerative disorder with insidious onset. Accurate prediction of the disease progression has received increasing attention. Cognitive scores that reflect patients' cognitive status have become important criteria for predicting AD. Most existing methods consider the relationship between neuroimages and cognitive scores to improve pr...Show More
Deep neural networks (DNNs) have achieved great success in many data processing applications. However, high computational complexity and storage cost make deep learning difficult to be used on resource-constrained devices, and it is not environmental-friendly with much power cost. In this paper, we focus on low-rank optimization for efficient deep learning techniques. In the space domain, DNNs are...Show More
The tensor singular value decomposition (t-SVD) based incomplete multi-view clustering (IMVC) has received wide attention due to its ability to capture high-order correlations. However, t-SVD suffers from rotation sensitivity, failing to fully explore both inter- and intra-view consistencies. Besides, current methods mainly consider inter- or intra-view correlations, ignoring the low-rank informat...Show More
Tensor decomposition is widely used in feature extraction, data analysis, and other fields. As a means of tensor decomposition, the robust tensor power method based on tensor sketch (TS-RTPM) can quickly mine the potential features of tensor, but in some cases, its approximation performance is limited. In this paper, we propose a data-driven framework called TS-RTPM-Net, which improves the estimat...Show More
Tensor-based multi-view subspace clustering (MSC) can capture high-order correlation in the self-representation tensor. Current tensor decompositions for MSC suffer from highly unbalanced unfolding matrices or rotation sensitivity, failing to fully explore inter/intra-view information. Using the advanced tensor network, namely, multi-scale entanglement renormalization ansatz (MERA), we propose a l...Show More
