Near-Optimal Bounds for Generalized Orthogonal Procrustes Problem via Generalized Power Method
Shuyang Ling
Given multiple point clouds, how to find the rigid transform (rotation, reflection, and shifting) such that these point clouds are well aligned? This problem, known as the generali…
Generalized Orthogonal Procrustes Problem under Arbitrary Adversaries
Shuyang Ling
The generalized orthogonal Procrustes problem (GOPP) plays a fundamental role in several scientific disciplines including statistics, imaging science and computer vision. Despite i…
Improved Performance Guarantees for Orthogonal Group Synchronization via Generalized Power Method
Shuyang Ling
Given the noisy pairwise measurements among a set of unknown group elements, how to recover them efficiently and robustly? This problem, known as group synchronization, has drawn t…
Near-Optimal Performance Bounds for Orthogonal and Permutation Group Synchronization via Spectral Methods
Shuyang Ling
Group synchronization asks to recover group elements from their pairwise measurements. It has found numerous applications across various scientific disciplines. In this work, we fo…
Regularized Gradient Descent: A Nonconvex Recipe for Fast Joint Blind Deconvolution and Demixing
Shuyang Ling, Thomas Strohmer
We study the question of extracting a sequence of functions from observing only the sum of their convolutions, i.e., from $\boldsym…
Self-Calibration and Bilinear Inverse Problems via Linear Least Squares
Shuyang Ling, Thomas Strohmer
Whenever we use devices to take measurements, calibration is indispensable. While the purpose of calibration is to reduce bias and uncertainty in the measurements, it can be quite…
