In this paper, the problem of residual variance estimation is examined. The problem is analyzed in a general setting which covers non-additive heteroscedastic noise under non-iid s...
We present a complex scheduling problem where we want to plan meetings between customers and exhibitors at a trade event. One cause of the complexity of the problem is the general...
Abstract. In this paper we study dualities of graphs and, more generally, relational structures with respect to full homomorphisms, that is, mappings that are both edge- and non-ed...
We consider the problem of indexing general database workloads (combinations of data sets and sets of potential queries). We dene a framework for measuring the eciency of an ind...

Assume a network (V, E) where a subset of the nodes in V are active. We consider the problem of selecting a set of k active nodes that best explain the observed activation state, ...
