A Unified SVD-Modal Solution for Sparse Sound Field Reconstruction with Hybrid Spherical-Linear Microphone Arrays

Shunxi Xu, Thushara Abhayapala, Craig Jin

ICASSP 2026poster

We propose a data-driven sparse recovery framework for hybrid spherical linear microphone arrays using singular value decomposition (SVD) of the transfer operator. The SVD yields orthogonal microphone and field modes, reducing to spherical harmonics (SH) in the SMA-only case, while incorporating LMA…

A Linear-time Independence Criterion Based on a Finite Basis Approximation

Longfei Yan, W. Bastiaan Kleijn, Thushara Abhayapala

AISTATS 2020poster

Detection of statistical dependence between random variables is an essential component in many machine learning algorithms. We propose a novel independence criterion for two random variables with linear-time complexity. We establish that our independence criterion is an upper bound of the Hirschfeld…
