Max van Mulken, Bettina Speckmann, Kevin Verbeek
Sets of moving entities can form groups which travel together for significant amounts of time. Tracking such groups is an important analysis task in a variety of areas, such as wil…
Agglomerative Clustering of Growing Squares
Thom Castermans, Bettina Speckmann, Frank Staals +1
We study an agglomerative clustering problem motivated by interactive glyphs in geo-visualization. Consider a set of disjoint square glyphs on an interactive map. When the user zoo…
A Framework for Algorithm Stability
Wouter Meulemans, Bettina Speckmann, Kevin Verbeek +1
We say that an algorithm is stable if small changes in the input result in small changes in the output. This kind of algorithm stability is particularly relevant when analyzing and…
