Center node: "on the compressibility of affinely singular random vectors"
  Abstract: There are several ways to measure the compressibility of a random measure; they include the general rate-distortion curve, as well as more specific notions such as Renyi information dimension (RID), and dimensional-rate bias (DRB). The RID parameter indicates the concentration of the measure around lower-dimensional subsets of the space while the DRB parameter specifies the compressibility of the distribution over these lower-dimensional subsets. While the evaluation of such compressibility parameters is well-studied for continuous and discrete measures (e.g., the DRB is closely related to the entropy and differential entropy in discrete and continuous cases, respectively), the case of discrete-continuous measures is quite subtle. In this paper, we focus on a class of multi-dimensional random measures that have singularities on affine lower-dimensional subsets. These cases are of interest when working with linear transformation of component-wise independent discrete-continuous random variables. Here, we evaluate the RID and DRB for such probability measures. We further provide an upper-bound for the RID of multi-dimensional random measures that are obtained by Lipschitz functions of component-wise independent discrete-continuous random variables ($\mathbf{x}$). The upper-bound is shown to be achievable when the Lipschitz function is $A \mathbf{x}$, where $A$ satisfies $\spark({A}) = \rank ({A})+1$ (e.g., Vandermonde matrices). The above results in the case of discrete-domain moving-average processes with non-Gaussian excitation noise allow us to evaluate the block-average RID and to find a relationship between this parameter and other existing compressibility measures.
