Crystal Image Analysis based on Fast Synchrosqueezed Transforms
Tao Zhang, Ling Li, Haizhao Yang
We propose an efficient algorithm to analyze atomic resolution crystal images based on a fast synchrosqueezed wave packet transform. The proposed algorithm can automatica…
Interpolative Decomposition Butterfly Factorization
Qiyuan Pang, Kenneth L. Ho, Haizhao Yang
This paper introduces a "kernel-independent" interpolative decomposition butterfly factorization (IDBF) as a data-sparse approximation for matrices that satisfy a complementary low…
PiPs: a Kernel-based Optimization Scheme for Analyzing Non-Stationary 1D Signals
Jieren Xu, Yitong Li, Haizhao Yang +2
This paper proposes a novel kernel-based optimization scheme to handle tasks in the analysis, e.g., signal spectral estimation and single-channel source separation of 1D non-statio…
Fast algorithms for Jacobi expansions via nonoscillatory phase functions
James Bremer, Haizhao Yang
We describe a suite of fast algorithms for evaluating Jacobi polynomials, applying the corresponding discrete Sturm-Liouville eigentransforms and calculating Gauss-Jacobi quadratur…
A Unified Framework for Oscillatory Integral Transform: When to use NUFFT or Butterfly Factorization?
Haizhao Yang
This paper concerns the fast evaluation of the matvec for , which is the discretization of the oscillatory integral transform $g(x) = \int K(x,ξ…
