Multidimensional Butterfly Factorization
Yingzhou Li, Haizhao Yang, Lexing Ying
This paper introduces the multidimensional butterfly factorization as a data-sparse representation of multidimensional kernel matrices that satisfy the complementary low-rank prope…
Butterfly Factorization
Yingzhou Li, Haizhao Yang, Eileen Martin +2
The paper introduces the butterfly factorization as a data-sparse approximation for the matrices that satisfy a complementary low-rank property. The factorization can be constructe…
Combining synchrosqueezed wave packet transform with optimization for crystal image analysis
Jianfeng Lu, Benedikt Wirth, Haizhao Yang
We develop a variational optimization method for crystal analysis in atomic resolution images, which uses information from a 2D synchrosqueezed transform (SST) as input. The synchr…
