Unified Transformed t-SVD Using Unfolding Tensors for Visual Inpainting
Low-rank tensor completion (LRTC) restores missing elements in multidimensional visual data; the challenge is representing the inherent structures within this data.

A Hybrid Norm for Guaranteed Tensor Recovery
Benefiting from the superiority of tensor Singular Value Decomposition (t-SVD) in excavating low-rankness in the spectral domain over other tensor decompositions (like Tucker decomposition), t-SVD-based tensor learning has shown promising performance and

DTI-ALPS as a Biomarker of Small Vessel Disease Progression and Amyloid-β in Normal Aging: A 3-Year Longitudinal Study. [PDF]
A higher DTI‐derived ALPS index relates cross‐sectionally to both quantitative and visual measures of SVD and is associated with short‐term amyloid‐β accumulation in cognitively normal older adults. Also, greater amyloid burden and choroid plexus volume are associated with a more rapid deterioration in global cognition and processing speed.

Online Tensor Robust Principal Component Analysis
Online robust principal component analysis (RPCA) algorithms recursively decompose incoming data into low-rank and sparse components. However, they operate on data vectors and cannot directly be applied to higher-order data arrays (e.g. video frames). In

A Deep Nonlinear Subspace Modeling and Reconstruction for Diffusion-Weighted Imaging Using Denoising Auto-Encoder. [PDF]
ABSTRACT Purpose To present a novel, nonlinear subspace modeling and joint k–q‐space reconstruction technique for high‐resolution, multi‐band, multi‐shell diffusion‐weighted imaging (DWI). Methods High b‐value (> 1000 s/mm2), high resolution DWI has the drawback of generally low signal‐to‐noise ratios (SNRs).
