Optimal Detection of Random Walks on Graphs: Performance Analysis via Statistical Physics
Ameya Agaskar, Yue M. Lu
We study the problem of detecting a random walk on a graph from a sequence of noisy measurements at every node. There are two hypotheses: either every observation is just meaningle…

Sampling Sparse Signals on the Sphere: Algorithms and Applications
Ivan Dokmanic, Yue M. Lu
We propose a sampling scheme that can perfectly reconstruct a collection of spikes on the sphere from samples of their lowpass-filtered observations. Central to our algorithm is a…

Randomized Kaczmarz Algorithm for Inconsistent Linear Systems: An Exact MSE Analysis
Chuang Wang, Ameya Agaskar, Yue M. Lu
We provide a complete characterization of the randomized Kaczmarz algorithm (RKA) for inconsistent linear systems. The Kaczmarz algorithm, known in some fields as the algebraic rec…
