In many domains data items are represented by vectors of counts; count data arises, for example, in bioinformatics or analysis of text documents represented as word count vectors. However, often the amount of data available from an interesting data source is too small to model the data source well. When several data sets are available from related sources, exploiting their similarities by trans...

We model dependencies between m multivariate continuous-valued information sources by a combination of (i) a generalized canonical correlations analysis (gCCA) to reduce dimensionality while preserving dependencies in m − 1 of them, and (ii) summarizing dependencies with the remaining one by associative clustering. This new combination of methods avoids multiway associative clustering which wou...

This paper describes a qualitative, explorative study of how students understand some concepts in concurrent programming. The study is based on interviews with students regarding the final programming assignment in a concurrent programming course. We use phenomenography to analyse the students’ statements about tuple spaces, the concurrent data structures on which the assignments are based, and...

The precise computation of abstractions is a bottleneck in many approaches to CEGAR-based verification. In this paper, we propose a novel approach, based on the use of structural information. Rather than computing the abstraction as a single, monolithic quantification, we provide a structure-aware abstraction algorithm, based on two complementary steps. The first, highlevel step exploits the st...

The complexity of modern enterprise networks is ever-increasing, and our understanding of these important networks is not keeping pace. Our insight into intra-subnet traffic (staying within a single LAN) is particularly limited, due to the widespread use of Ethernet switches that preclude ready LAN-wide monitoring. We have recently undertaken an approach to obtaining extensive intra-subnet visi...

The financial perfonnance of gaming stocks during the past year has been good to excellent and occasionally spectacular. As a group, the gaming stocks rose 49.9 percent. Major industry players with strong cash flows, nationally known franchises, and depth of management are positioned best to continue to increase in value as they expand into new locations, particular locations close to large pop...

Exponential family extensions of principal component analysis (EPCA) have received a considerable amount of attention in recent years, demonstrating the growing need for basic modeling tools that do not assume the squared loss or Gaussian distribution. We extend the EPCA model toolbox by presenting the first exponential family multi-view learning methods of the partial least squares and canonic...
