Fast Multiscale Functional Estimation in Optimal EMG Placement for Robotic Prosthesis Controllers
Jin Ren, Guohui Song, Lucia Tabacu +1
Electrocardiogram (EMG) signals play a significant role in decoding muscle contraction information for robotic hand prosthesis controllers. Widely applied decoders require large am…
Sparse Regularization with the Norm
Yuesheng Xu
We consider a minimization problem whose objective function is the sum of a fidelity term, not necessarily convex, and a regularization term defined by a positive regularization pa…
Multiplicative Noise Removal: Nonlocal Low-Rank Model and Its Proximal Alternating Reweighted Minimization Algorithm
Xiaoxia Liu, Jian Lu, Lixin Shen +2
The goal of this paper is to develop a novel numerical method for efficient multiplicative noise removal. The nonlocal self-similarity of natural images implies that the matrices f…
Two-step Fixed-point proximity algorithms for multi-block separable convex problems
Qia Li, Yuesheng Xu, Na Zhang
Multi-block separable convex problems recently received considerable attention. This class of optimization problems minimizes a separable convex objective function with linear cons…
