Robust recovery of bandlimited graph signals via randomized dynamical sampling

Longxiu Huang, Deanna Needell, Sui Tang

Heat diffusion processes have found wide applications in modelling dynamical systems over graphs. In this paper, we consider the recovery of a -bandlimited graph signal that is…

Predictive algorithms in dynamical sampling for burst-like forcing terms

Akram Aldroubi, Longxiu Huang, Keri Kornelson +1

In this paper, we consider the problem of recovery of a burst-like forcing term in an initial value problem (IVP) in the framework of dynamical sampling. We introduce an idea of us…

Fast Robust Tensor Principal Component Analysis via Fiber CUR Decomposition

HanQin Cai, Zehan Chao, Longxiu Huang +1

We study the problem of tensor robust principal component analysis (TRPCA), which aims to separate an underlying low-multilinear-rank tensor and a sparse outlier tensor from their…

Rapid Robust Principal Component Analysis: CUR Accelerated Inexact Low Rank Estimation

HanQin Cai, Keaton Hamm, Longxiu Huang +2

Robust principal component analysis (RPCA) is a widely used tool for dimension reduction. In this work, we propose a novel non-convex algorithm, coined Iterated Robust CUR (IRCUR),…
