      High-dimensional data sets are a prevalent occurrence in many application domains. This data is commonly visualized using dimensionality reduction (DR) methods. DR methods provide e.g. a two-dimensional embedding of the ...
    • Map-based Visualizations Increase Recall Accuracy of Data 

      Saket, Bahador; Scheidegger, Carlos; Kobourov, Stephen G.; Börner, Katy (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We investigate the memorability of data represented in two different visualization designs. In contrast to recent studies that examine which types of visual information make visualizations memorable, we examine the effect ...
    • Feature-Driven Visual Analytics of Chaotic Parameter-Dependent Movement 

      Luboschik, Martin; Röhlig, Martin; Bittig, Arne T.; Andrienko, Natalia; Schumann, Heidrun; Tominski, Christian (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Analyzing movements in their spatial and temporal context is a complex task. We are additionally interested in understanding the movements' dependency on parameters that govern the processes behind the movement. We propose ...
    • Visual Analytics for Correlation-Based Comparison of Time Series Ensembles 

      Köthur, Patrick; Witt, Carl; Sips, Mike; Marwan, Norbert; Schinkel, Stefan; Dransch, Doris (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      An established approach to studying interrelations between two non-stationary time series is to compute the 'windowed' cross-correlation (WCC). The time series are divided into intervals and the cross-correlation between ...
    • A Novel Framework for Visual Detection and Exploration of Performance Bottlenecks in Organic Photovoltaic Solar Cell Materials 

      Aboulhassan, Amal; Baum, Daniel; Wodo, Olga; Ganapathysubramanian, Baskar; Amassian, Aram; Hadwiger, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Current characterization methods of the so-called Bulk Heterojunction (BHJ), which is the main material of Organic Photovoltaic (OPV) solar cells, are limited to the analysis of global fabrication parameters. This reduces ...
    • A Shot at Visual Vulnerability Analysis 

      Kerzner, Ethan; Butler, Lee A.; Hansen, Charles; Meyer, Miriah (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Increasing the safety of vehicles is an important goal for vehicle manufacturers. These manufacturers often turn to simulations to understand how to improve a vehicle's design as real-world safety tests are expensive and ...
