On the relaxed greedy randomized Kaczmarz methods with momentum acceleration for solving matrix equation AXB=C
Nian-Ci Wu, Yang Zhou, Zhaolu Tian
With the growth of data, it is more important than ever to develop an efficient and robust method for solving the consistent matrix equation AXB=C. The randomized Kaczmarz (RK) met…
Randomized progressive iterative approximation for B-spline curve and surface fittings
Nian-Ci Wu, Chengzhi Liu
For large-scale data fitting, the least-squares progressive iterative approximation is a widely used method in many applied domains because of its intuitive geometric meaning and e…
On the Polyak momentum variants of the greedy deterministic single and multiple row-action methods
Nian-Ci Wu, Qian Zuo, Yatian Wang
For solving a consistent system of linear equations, the classical row-action (also known as Kaczmarz) method is a simple while really effective iteration solver. Based on the gree…
Asynchronous progressive iterative approximation method for least-squares fitting
Nian-Ci Wu, Cheng-Zhi Liu
For large-scale data fitting, the least-squares progressive-iterative approximation (LSPIA) methods were proposed by Lin et al. (SIAM Journal on Scientific Computing, 2013, 35(6):A…
On the extended randomized multiple row method for solving linear least-squares problems
Nian-Ci Wu, Chengzhi Liu, Yatian Wang +1
The randomized row method is a popular representative of the iterative algorithm because of its efficiency in solving the overdetermined and consistent systems of linear equations.…
On the relaxed greedy deterministic row and column iterative methods
Nian-Ci Wu, Ling-Xia Cui, Qian Zuo
For solving the large-scale linear system by iteration methods, we utilize the Petrov-Galerkin conditions and relaxed greedy index selection technique and provide two relaxed greed…
Randomized QLP algorithm and error analysis
Nianci Wu, Hua Xiang
In this paper, we describe the randomized QLP (RQLP) algorithm and its enhanced version (ERQLP) for computing the low rank approximation to of size efficiently such…
