An interactive multi-display cluster-style rendering system is presented which runs on a single PC rather than a cluster of PCs. Many Direct3D features, including support for a programmable pipeline, are supported via a drop-in library replacement for Direct3D. While the presented profiling results are bandwidth limited, PCI cards have been used. It is expected that the greater bandwidth of PCI...

Word clustering which generalizes specific features cluster words in the same syntactic or semantic categories into a group. It is an effective approach to reduce feature dimensionality and feature sparseness which are clearly useful for many NLP applications. This paper proposes an unsupervised label propagation algorithm (Un-LP) for word clustering which uses multi-exemplars to represent a cl...

Abstract. An application of cluster analysis to identify topics in a collection of posters abstracts from the Society for Neuroscience (SfN) Annual Meeting in 2006 is presented. The topics were identified by selecting from the abstracts belonging to each cluster the terms with the highest scores using different ranking schemes. The ranking scheme based on logentropy showed better performance in...

This study examines categorical and spatial patterns for trending venues in three cities. The three cities in our experiment are New York City, NY, Pittsburgh, PA and Erie, PA. We examine common categories of venues that trend in our test cities and see a similar theme in each city favoring foodbased venues, nightlife venues and other venues. We map the venues in each city and perform a nearest...
