Contrastive Learning for Large-scale Color-Name Dataset: Tackling Sparsity with Negative Sampling

Large-scale color datasets exhibit significant sparsity in name-color correspondences, substantially impeding the effectiveness of conventional methodologies. We propose a contrastive learning-based framework for color name generation and recommendation that addresses sparsity through negative sampling, supporting two…

Libra: An Interaction Model for Data Visualization

While existing visualization libraries enable the reuse, extension, and combination of static visualizations, achieving the same for interactions remains nearly impossible. We contribute an interaction model and its implementation to achieve this goal. Our model enables the creation of interactions that support direc…

Semi-transparent visualizations are commonly used to reveal information in overlapped regions by applying colors and opacity. While a few studies made recommendations on how to choose colors and opacity levels to maintain depth perception, they often conflict and overlook the interaction effect between these factors.…
