    • Attribute-based Visual Explanation of Multidimensional Projections 

      Silva, Renato R. O. da; Rauber, Paulo E.; Martins, Rafael M.; Minghim, Rosane; Telea, Alexandru C. (The Eurographics Association, 2015)
      Multidimensional projections (MPs) are key tools for the analysis of multidimensional data. MPs reduce data dimensionality while keeping the original distance structure in the low-dimensional output space, typically shown ...
    • Capturing Reasoning Process through User Interaction 

      Dou, Wenwen; Ribarsky, William; Chang, Remco (The Eurographics Association, 2010)
      In recent years, visual analytics has taken an important role in solving many types of complex analytical problems that require deep and specific domain knowledge from users. While the analysis products generated by these ...
    • Characterizing Visual Analytics in Diagnostic Imaging 

      Lundström, C.; Persson, A. (The Eurographics Association, 2011)
      Many necessary and desired improvements in healthcare are dependent on progress in medical imaging. As shown in this paper, the challenges targeted by visual analytics (VA) coincide with main challenges for radiologists' ...
    • Combining Cluster and Outlier Analysis with Visual Analytics 

      Bernard, Jürgen; Dobermann, Eduard; Sedlmair, Michael; Fellner, Dieter W. (The Eurographics Association, 2017)
      Cluster and outlier analysis are two important tasks. Due to their nature these tasks seem to be opposed to each other, i.e., data objects either belong to a cluster structure or a sparsely populated outlier region. In ...
    • Combining Details of the Chi-Square Goodness-of-Fit Test with Multivariate Data Visualization 

      May, Thorsten; Davey, James; Kohlhammer, Jörn (The Eurographics Association, 2010)
      In this work, we combine KVMaps, a visualization technique presented in [May07] for the visualization of statistical aggregations in multivariate contingency tables, with the measures used for the statistical Chi-Square ...
    • Combining the Automated Segmentation and Visual Analysis of Multivariate Time Series 

      Bernard, Jürgen; Bors, Christian; Bögl, Markus; Eichner, Christian; Gschwandtner, Theresia; Miksch, Silvia; Schumann, Heidrun; Kohlhammer, Jörn (The Eurographics Association, 2018)
      For the automatic segmentation of multivariate time series domain experts at first need to consider a huge space of alternative configurations of algorithms and parameters. We assume that only a small subset of these ...
    • ComModeler: Topic Modeling Using Community Detection 

      Dang, Tommy; Nguyen, Vinh The (The Eurographics Association, 2018)
      This paper introduces ComModeler, a novel approach for topic modeling using community finding in dynamic networks. Our algorithm first extracts the terms/keywords, formulates a network of collocated terms, then refines the ...
    • Comparative Visual Analysis of Cross-Linguistic Features 

      Rohrdantz, Christian; Mayer, Thomas; Butt, Miriam; Plank, Frans; Keim, Daniel A. (The Eurographics Association, 2010)
      Approaches in Visual Analytics have so far been developed for a wide array of research areas, mainly with a focus on industrial or business applications. The field of linguistics, however, has only marginally incorporated ...
    • A Concept for Consensus-based Ordering of Views 

      Jentner, Wolfgang; Jäckle, Dominik; Engelke, Ulrich; Keim, Daniel A.; Schreck, Tobias (The Eurographics Association, 2018)
      High-dimensional data poses a significant challenge for analysis, as patterns typically exist only in subsets of dimensions or records. A common approach to reveal patterns, such as meaningful structures or relationships, ...
    • Contextualized Analysis of Movement Events 

      Chen, Siming; Andrienko, Gennady; Andrienko, Natalia; Doulkeridis, Christos; Koumparos, Athanasios (The Eurographics Association, 2019)
      For understanding the circumstances, causes, and consequences of events that may happen during movement (e.g., harsh brake, sharp turn), it is necessary to analyze event context. The context includes dynamic attributes of ...
    • Contingency Wheel: Visual Analysis of Large Contingency Tables 

      Alsallakh, Bilal; Groeller, Eduard; Miksch, Silvia; Suntinger, Martin (The Eurographics Association, 2011)
      We present the Contingency Wheel, a visual method for finding and analyzing associations in a large nxm contingency table with m less than 100 and n being two to three orders of magnitude larger than m. The method is ...
    • Data Driven Color Mapping 

      Eisemann, Martin; Albuquerque, Georgia; Magnor, Marcus (The Eurographics Association, 2011)
