On construction and analysis of sparse random matrices and expander graphs with applications to compressed sensing
Bubacarr Bah, Jared Tanner
We revisit the probabilistic construction of sparse random matrices where each column has a fixed number of nonzeros whose row indices are drawn uniformly at random. These matrices…

Energy-aware adaptive bi-Lipschitz embeddings
Bubacarr Bah, Ali Sadeghian, Volkan Cevher
We propose a dimensionality reducing matrix design based on training data with constraints on its Frobenius norm and number of rows. Our design criteria is aimed at preserving the…
