      Embedding and visualizing large-scale high-dimensional data in a two-dimensional space is an important problem, because such visualization can reveal deep insights of complex data. However, most of the existing embedding ...

    • Interactive Analysis of Word Vector Embeddings 

      Heimerl, Florian; Gleicher, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Word vector embeddings are an emerging tool for natural language processing. They have proven beneficial for a wide variety of language processing tasks. Their utility stems from the ability to encode word relationships ...

    • Exploring High-Dimensional Structure via Axis-Aligned Decomposition of Linear Projections 

      Thiagarajan, Jayaraman J.; Liu, Shusen; Ramamurthy, Karthikeyan Natesan; Bremer, Peer-Timo (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Two-dimensional embeddings remain the dominant approach to visualize high dimensional data. The choice of embeddings ranges from highly non-linear ones, which can capture complex relationships but are difficult to interpret ...

    • Hypersliceplorer: Interactive Visualization of Shapes in Multiple Dimensions 

      Torsney-Weir, Thomas; Möller, Torsten; Sedlmair, Michael; Kirby, R. Mike (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In this paper we present Hypersliceplorer, an algorithm for generating 2D slices of multi-dimensional shapes defined by a simplical mesh. Often, slices are generated by using a parametric form and then constraining parameters ...

    • ConcaveCubes: Supporting Cluster-based Geographical Visualization in Large Data Scale 

      Li, Mingzhao; Choudhury, Farhana; Bao, Zhifeng; Samet, Hanan; Sellis, Timos (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In this paper we study the problem of supporting effective and scalable visualization for the rapidly increasing volumes of urban data. From an extensive literature study, we find that the existing solutions suffer from ...

    • Bladder Runner: Visual Analytics for the Exploration of RT-Induced Bladder Toxicity in a Cohort Study

    • Visual and Quantitative Analysis of Great Arteries' Blood Flow Jets in Cardiac 4D PC-MRI Data 

      Köhler, Benjamin; Grothoff, Matthias; Gutberlet, Matthias; Preim, Bernhard (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Flow in the great arteries (aorta, pulmonary artery) is normally laminar with a parabolic velocity profile. Eccentric flow jets are linked to various diseases like aneurysms. Cardiac 4D PC-MRI data provide spatio-temporally ...

    • Explorative Blood Flow Visualization using Dynamic Line Filtering based on Surface Features 

      Behrendt, Benjamin; Berg, Philipp; Beuing, Oliver; Preim, Bernhard; Saalfeld, Sylvia (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Rupture risk assessment is a key to devise patient-specific treatment plans of cerebral aneurysms. To understand and predict the development of aneurysms and other vascular diseases over time, both hemodynamic flow patterns ...
