Iteratively reweighted algorithms for compressive sensing
The theory of compressive sensing has shown that sparse signals can be reconstructed exactly from many fewer measurements than traditionally believed necessary. In [1], it was sho...

Investigating the use of summarisation for interactive XML retrieval
As the number of components in XML documents is much larger than that of ‘flat’ documents, we believe it is essential to provide users of XML information retrieval systems wi...

On the Complexity of Probabilistic Inference in Singly Connected Bayesian Networks
Abstract. In this paper, we revisit the consensus of computational complexity on exact inference in Bayesian networks. We point out that even in singly connected Bayesian networks,...
