Sketched Clustering via Hybrid Approximate Message Passing
Evan Byrne, Antoine Chatalic, Remi Gribonval +1
In sketched clustering, a dataset of samples is first sketched down to a vector of modest size, from which the centroids are subsequently extracted. Advantages include i) reduc…
Beyond Moore-Penrose Part II: The Sparse Pseudoinverse
Ivan Dokmanić, Rémi Gribonval
This is the second part of a two-paper series on generalized inverses that minimize matrix norms. In Part II we focus on generalized inverses that are minimizers of entrywise p nor…
Beyond Moore-Penrose Part I: Generalized Inverses that Minimize Matrix Norms
Ivan Dokmanić, Rémi Gribonval
This is the first paper of a two-long series in which we study linear generalized inverses that minimize matrix norms. Such generalized inverses are famously represented by the Moo…
Compressed sensing in Hilbert spaces
Yann Traonmilin, Gilles Puy, Rémi Gribonval +1
In many linear inverse problems, we want to estimate an unknown vector belonging to a high-dimensional (or infinite-dimensional) space from few linear measurements. To overcome the…
