A nonparametric model is introduced that allows multiple related regression tasks to take inputs from a common data space. Traditional transfer learning models can be inappropriate if the dependence among the outputs cannot be fully resolved by known input-specific and task-specific predictors. The ...

The evacuation of whole cities or even regions is an important problem, as demonstrated by recent events such as the evacuation of Houston in the case of Hurricane Rita, or the evacuation of coastal cities in the case of tsunamis. A robust and flexible simulation framework for such large scale disas ...

The vascular structure of the retina consists of two kinds of vessels: arteries and veins. Together these vessels form the vascular graph. In this paper we present an approach to separating arteries and veins based on a pre-segmentation and a few hand-labelled vessel segments. We use a rule-based me ...

In the absence of explicit queries, an alternative is to try to infer users' interests from implicit feedback signals, such as clickstreams or eye tracking. The interests, formulated as an implicit query, can then be used in further searches. We formulate this task as a probabilistic model, which ca ...

Low-rank matrix approximation is an effective tool in alleviating the memory and computational burdens of kernel methods and sampling, as the mainstream of such algorithms, has drawn considerable attention in both theory and practice. This paper presents detailed studies on the Nystrom sampling sche ...

Practical data analysis and mining rarely falls exactly into the supervised learning scenario. Rather, the growing amount of unlabelled
data from various scientific domains poses a big challenge to large-scale semi-supervised learning (SSL). We note that the computational
intensiveness of graph-bas ...

The concept and theory of statistical significance testing is well established in a traditional setup, but not in the problem settings related to data mining. In this talk I discuss the formulation as well as advantages and limitations of the statistical significance testing approaches in data minin ...
