Efficiently rank and create quality colormaps tailored to individual user preferences using Cieran.
Zusammenfassung
Cieran introduces a tool for rapid colormap selection within Jupyter Notebooks.
The system employs active preference learning to rank and create colormaps.
Colormaps should be orderable, smooth, discriminable, and adhere to perceptual uniformity.
Challenges in colormap design include aesthetic appeal, color semantics, and chart variations.
Existing tools limit expressivity, leading to inadequate data presentation.
Cieran treats colormap design as a path planning problem in the CIELAB colorspace.
The system validates its technical approaches through a user study with domain experts.
Cieran's workflow involves seed color selection, expert-designed colormap fitting, pairwise comparisons, ranking, and new colormap creation.
Automation can support effective visualization design.
Human-in-the-loop approaches like ViA incorporate personal preferences into visualization recommendations.
Preference-based design optimization leverages active learning to rank and create colormaps.
Cieran's user interface allows for efficient colormap customization within Jupyter Notebooks.
Statistiken
Quality colormaps can help communicate important data patterns.
Cieran employs an active preference learning paradigm to rank expert-designed colormaps and create new ones from pairwise comparisons.
In an evaluation with twelve scientists, Cieran effectively modeled user preferences to rank colormaps and create new quality designs.
