The paper “Improving Population Monte Carlo: Alternative Weighting and Resampling Schemes” by  V. Elvira, L. Martino, D. Luengo, and M. Bugallo has been accepted for publication in Signal Processing Abstract: Population Monte Carlo (PMC) sampling methods are powerful tools for approximating distributions of static unknowns given a set of observations. These methods are iterative in nature: at…

A new paper from the group has been accepted for publication The paper “The Shannon lower bound is asymptotically tight” by T. Koch has been accepted for publication in the IEEE Transactions on Information Theory. Abstract: The Shannon lower bound is one of the few lower bounds on the rate-distortion function that holds for a…

A new paper from the group has been accepted for publication The paper “Layered Adaptive Importance Sampling” by L. Martino, V. Elvira, D. Luengo, and J. Corander has been accepted for publication in Statistics and Computing. Abstract: Monte Carlo methods represent the «de facto» standard for approximating complicated integrals involving multidimensional target distributions. In order to generate random realizations from…
