In this wide-ranging discussion, panelists seized on redesigning science education as a way of ensuring the success of systems biology. The first challenge lies in improving instruction in the earliest years. David Botstein said, “K-12 education has never been that great…(kids) don’t need to know ev ...

This paper examines social structures underlying economic activity in Second Life (SL), a massively multiplayer virtual world that allows users to create and trade virtual objects and commodities. We find that users conduct many of their transactions both within their social networks and within grou ...

A justification for an entailment in an OWL ontology is a minimal subset of the ontology that is sufficient for that entailment to hold. Since justifications respect the syntactic form of axioms in an ontology, they are usually neither syntactically nor semantically minimal. This paper presents two ...

In this paper, we present an approach to determining the cognitive
complexity of justifications for entailments of OWL ontologies. We introduce
a simple cognitive complexity model and present the results of validating that
model via experiments involving OWL users. The validation is based on test da ...

We study learning curves for Gaussian process regression which characterise performance in terms of the Bayes error averaged over datasets of a given size. Whilst learning curves are in general very difficult to calculate we show that for discrete input domains, where similarity between input points ...

How can we train a statistical mixture model on a massive data set? In this paper, we show how to construct coresets for mixtures of Gaussians and natural generalizations. A coreset is a weighted subset of the data, which guarantees that models fitting the coreset will also provide a good fit for th ...
