Linear Time Kernel Matrix Approximation via Hyperspherical Harmonics
John Paul Ryan, Anil Damle
We propose a new technique for constructing low-rank approximations of matrices that arise in kernel methods for machine learning. Our approach pairs a novel automatically construc…
The Fast Kernel Transform
John Paul Ryan, Sebastian Ament, Carla P. Gomes +1
Kernel methods are a highly effective and widely used collection of modern machine learning algorithms. A fundamental limitation of virtually all such methods are computations invo…
Parallel Skeletonization for Integral Equations in Evolving Multiply-Connected Domains
John Paul Ryan, Anil Damle
This paper presents a general method for applying hierarchical matrix skeletonization factorizations to the numerical solution of boundary integral equations with possibly rank-def…
Geometric frustration induces the transition between rotation and counterrotation in swirled granular media
Lisa Lee, John Paul Ryan, Yoav Lahini +2
Granular material in a swirled container exhibits a curious transition as the number of particles is increased: at low densities the particle cluster rotates in the same direction…
