    Cramér–Rao lower bounds arising from generalized Csiszár divergences

    We study the geometry of probability distributions with respect to a generalized family of Csiszár f-divergences. A member of this family is the relative \(\alpha \)α-entropy which is also a Rényi analog of relat...

    Computable performance guarantees for compressed sensing matrices

    The null space condition for ℓ1 minimization in compressed sensing is a necessary and sufficient condition on the sensing matrices under which a sparse signal can be uniquely recovered from the observation data v...
