Exploring the high dimensional geometry of HSI features

Wojciech Czaja, Ilya Kavalerov, Weilin Li

We explore feature space geometries induced by the 3-D Fourier scattering transform and deep neural network with extended attribute profiles on four standard hyperspectral images.…

Maximal function pooling with applications

Wojciech Czaja, Weilin Li, Yiran Li +1

Inspired by the Hardy-Littlewood maximal function, we propose a novel pooling strategy which is called maxfun pooling. It is presented both as a viable alternative to some of the m…

Generalization error of minimum weighted norm and kernel interpolation

Weilin Li

We study the generalization error of functions that interpolate prescribed data points and are selected by minimizing a weighted norm. Under natural and general conditions, we prov…

Three-Dimensional Fourier Scattering Transform and Classification of Hyperspectral Images

Ilya Kavalerov, Weilin Li, Wojciech Czaja +1

Recent developments in machine learning and signal processing have resulted in many new techniques that are able to effectively capture the intrinsic yet complex properties of hype…

Conditioning of restricted Fourier matrices and super-resolution of MUSIC

Weilin Li, Wenjing Liao

This paper studies stable recovery of a collection of point sources from its noisy low-frequency Fourier coefficients. We focus on the super-resolution regime where the minim…

Super-resolution limit of the ESPRIT algorithm

Weilin Li, Wenjing Liao, Albert Fannjiang

The problem of imaging point objects can be formulated as estimation of an unknown atomic measure from its consecutive noisy Fourier coefficients. The standard resolution of…
