Maximal ancestral graphs(MAGs) are used to encode conditional independence relations in DAG models with hidden variables. Di erent MAGs may represent the same set of con-ditional independences and are...

In this paper, we consider the problem of compressed sensing where the goal is to recover almost all the sparse vectors using a small number of fixed linear measurements. For this problem, we propose ...

Consider an ordered sample that is selected from
a finite population successively without replacement and with probability
proportional to some measure of size. In this paper, we study the
asymptot...
