Rewriting Ontological Queries into Small Nonrecursive Datalog Programs
Abstract. We consider the setting of ontological database access, where an Abox is given in form of a relational database D and where a Boolean conjunctive query q has to be evalua...

Simultaneous SDR optimality via a joint matrix decomposition
Abstract—This work considers the joint source-channel problem of transmitting a Gaussian source over a two-user multipleinput multiple-output (MIMO) broadcast channel. We show th...

Non-negative matrix deconvolution in noise robust speech recognition
High noise robustness has been achieved in speech recognition by using sparse exemplar-based methods with spectrogram windows spanning up to 300 ms. A downside is that a large exe...

Adjugate pairs of sparse arrays for sampling two dimensional signals
Sparse sampling with coprime lattice arrays was introduced recently in the literature. It has been shown that a dense coarray can be constructed from such a pair of arrays, and is...
