: Two main problems arise in modelling data warehouse structures. The first consists in establishing an adequate representation of dimensions in order to facilitate and to control ...
Complex objects can often be conveniently represented by finite sets of simpler components, such as images by sets of patches or texts by bags of words. We study the class of posi...
Unsupervised learning algorithms have been derived for several statistical models of English grammar, but their computational complexity makes applying them to large data sets int...
We present a visualization system allowing non-programmers to visualize, explore, and analyze unknown multivariate data by designing an appropriate glyph representation with minim...
In this paper, the collision prediction between polyhedra under screw motions and a static scene using a new K dimensional tree data structure (Multiresolution Kdtree, MKtree) is ...
