Multivariate confluent Vandermonde with G-Arnoldi and applications
Lei-Hong Zhang, Ya-Nan Zhang, Linyi Yang +1
In the least-squares fitting framework, the Vandermonde with Arnoldi (V+A) method presented in [Brubeck, Nakatsukasa, and Trefethen, {SIAM Review}, 63 (2021), pp. 405-415] is an ef…
The -weighted dual programming of the linear Chebyshev approximation and an interior-point method
Linyi Yang, Lei-Hong Zhang, Ya-Nan Zhang
Given samples of a real or complex-valued function on a set of distinct nodes, the traditional linear Chebyshev approximation is to compute the best minimax approximation on a pres…
A convex dual problem for the rational minimax approximation and Lawson's iteration
Lei-Hong Zhang, Linyi Yang, Wei Hong Yang +1
Computing the discrete rational minimax approximation in the complex plane is challenging. Apart from Ruttan's sufficient condition, there are few other sufficient conditions for g…
Masked conditional variational autoencoders for chromosome straightening
Jingxiong Li, Sunyi Zheng, Zhongyi Shui +9
Karyotyping is of importance for detecting chromosomal aberrations in human disease. However, chromosomes easily appear curved in microscopic images, which prevents cytogeneticists…
