Local Poisson Deconvolution for Discrete Signals

Authors Hundrieser S, Manole T, Litskevich D, Munk A Journal Arxiv Citation arXiv:2508.00824. Abstract We analyze the statistical problem of recovering an atomic signal, modeled as a discrete uniform distribution μ, from a binned Poisson convolution model. This question is motivated, among others, by super-resolution laser microscopy applications, where precise

Central limit theorems for the eigenvalues of graph Laplacians on data clouds

Authors Lui C, Trillos NG, Li H, Suchan L Journal Arxiv Citation arXiv:2507.18803. Abstract Given i.i.d.\ samples Xn={x1,…,xn} from a distribution supported on a low dimensional manifold M embedded in Eucliden space, we consider the graph Laplacian operator Δn associated to an ε-proximity graph over Xn and study the asymptotic
