Latent variable mixture models are a powerful tool for exploring the structure in large datasets. A common challenge for interpreting such models is a desire to impose sparsity, the natural assumption that each data point only contains few latent features. Since mixture distributions are constrained in their L 1 norm, typical sparsity techniques based on L… (More)
Exendin-4 is a glucagon-like receptor 1 agonist clinically used against type 2 diabetes that has also shown neuroprotective effects in experimental stroke models. However, while the neuroprotective efficacy of Exendin-4 has been thoroughly investigated if the pharmacological treatment starts before stroke, the therapeutic potential of the Exendin-4 if the… (More)
Team Avatar, as the members of Project Avatar have come to be known by, is a group of 4th year computer science students at Uppsala University that have been developing a distributed mobile phone game during the fall of 2005. In this paper we describe the general design and environment of the result of Project Avatar — the game Three Crowns.
