Difference-of-Convex Regularization for Graph Learning by Differentiable Programming
Liping Tao, Chee Wei Tan
Laplacian-regularized minimization is fundamental in signal processing and machine learning, but is limited by the dense and ill-conditioned nature of the graph Laplacian pseudoinv…
Learning to Optimize by Differentiable Programming
Liping Tao, Xindi Tong, Chee Wei Tan
Solving massive-scale optimization problems requires scalable first-order methods with low per-iteration cost. This tutorial highlights a shift in optimization: using differentiabl…
Learning-Based Spectrum Cartography in Low Earth Orbit Satellite Networks: An Overview
Liping Tao, Xindi Tong, Chee Wei Tan
Low earth orbit (LEO) satellite networks are emerging as a key infrastructure for global connectivity and space-based sensing. Many tasks in such systems can be formulated as measu…
Accelerating Regularized Attention Kernel Regression for Spectrum Cartography
Liping Tao, Chee Wei Tan
Spectrum cartography reconstructs spatial radio fields from sparse and heterogeneous wireless measurements, underpinning many sensing and optimization tasks in wireless networks. A…
