Lossless Representation of Topological Spatial Data
We present a data structure used to represent planar spatial databases in the topological data model. Conceptually, such databases consist of points, lines between these points, an...

Adding Control-Flow to a Visual Data-Flow Representation
Previous studies have shown that novices do not tend to extract or use data-flow information during program comprehension. However, for impact analysis and similar tasks, data-ï¬...

Manifold Denoising as Preprocessing for Finding Natural Representations of Data
A natural representation of data is given by the parameters which generated the data. If the space of parameters is continuous, then we can regard it as a manifold. In practice, w...

Efficient multidimensional data representations based on multiple correspondence analysis
In the On Line Analytical Processing (OLAP) context, exploration of huge and sparse data cubes is a tedious task which does not always lead to efficient results. In this paper, we...
