Randomized iterative methods with Polyak step-size for solving generalized absolute value equations
Jiayun Chen, Qiye Zhang, Deren Han +1
In this paper, we systematically incorporate the Polyak step-size into the randomized iterative method to improve its efficiency for solving generalized absolute value equations. I…
Two improved algorithms for sparse generalized canonical correlation analysis
Kuo-Yue Li, Qi-Ye Zhang, Yong-Han Sun
Regularized generalized canonical correlation analysis (RGCCA) is a generalization of regularized canonical correlation analysis to three or more sets of variables, which is a comp…
A re-examination to the SCoTLASS problems for SPCA and two projection-based methods for them
Qiye Zhang, Kuoyue Li
SCoTLASS is the first sparse principal component analysis (SPCA) model which imposes extra l1 norm constraints on the measured variables to obtain sparse loadings. Due to the the d…
Randomized block Kaczmarz with volume sampling: Momentum acceleration and efficient implementation
Ruike Xiang, Jiaxin Xie, Qiye Zhang
The randomized block Kaczmarz (RBK) method is a widely utilized iterative scheme for solving large-scale linear systems. However, the theoretical analysis and practical effectivene…
