ibUMAP: Coherent and Scalable Field Evaluation for UMAP Optimization
Bin Chen, Yumeng Xue, Patrick Paetzold +2
UMAP achieves scalable layout optimization through stochastic negative sampling. However, this stochasticity can lead to unstable embeddings across reruns and downstream reuse, as…
Structuring Line Ensembles with Path-Integrated Fidelity and Structural Inconsistency Fields
Yumeng Xue, Patrick Paetzold, Bin Chen +3
When visualizing large-scale line ensembles, trajectory continuity and visual scalability are inherently antagonistic. Trajectory-centric renderings preserve path information but r…
Enhancing Line Density Plots with Outlier Control and Bin-based Illumination
Yumeng Xue, Bin Chen, Patrick Paetzold +3
Density plots effectively summarize large numbers of points, which would otherwise lead to severe overplotting in, for example, a scatter plot. However, when applied to line-based…
Neighborhood-Preserving Voronoi Treemaps
Patrick Paetzold, Rebecca Kehlbeck, Yumeng Xue +3
Voronoi treemaps are used to depict nodes and their hierarchical relationships simultaneously. However, in addition to the hierarchical structure, data attributes, such as co-occur…
UADAPy: An Uncertainty-Aware Visualization and Analysis Toolbox
Patrick Paetzold, David Hägele, Marina Evers +2
Current research provides methods to communicate uncertainty and adapts classical algorithms of the visualization pipeline to take the uncertainty into account. Various existing vi…
The Categorical Data Map: A Multidimensional Scaling-Based Approach
Frederik L. Dennig, Lucas Joos, Patrick Paetzold +4
Categorical data does not have an intrinsic definition of distance or order, and therefore, established visualization techniques for categorical data only allow for a set-based or…
Reducing Ambiguities in Line-based Density Plots by Image-space Colorization
Yumeng Xue, Patrick Paetzold, Rebecca Kehlbeck +4
Line-based density plots are used to reduce visual clutter in line charts with a multitude of individual lines. However, these traditional density plots are often perceived ambiguo…
