June the 1st 2022. I have published on HAL a research report,

Title: "Importance Driven Color Assignment"

Subtitle: "Importance Driven Color-Group Assignment in Categorical Visualization"

on my latest work about assigning colors to classes for categorical data visualizations.

February the 17th, 2023. With the publication of a paper in the conference IVAPP2023, I just publish, on GitLab, an R language package for class-color assignment in categorical visualization.

Hypertubes and reduction operators in constraint solving

The thesis of M. Christie (co-supervised with F. Benhamou) defended in 2003 was the occasion for a theoretical deepening on interval techniques.

In 2014, the need for projection from multi-dimensional spaces toward 2D or 3D appears. From the 12 audio indicators provided by Echonest (now within spotify) to 2 dimensions or else 1 dimension. We had already used PCA (principal Component Analysis) but Self Organizing Map (SOM) and their algorithms were fascinating.

DUKe, my research team, is part of LS2N which is mostly located in Nantes, France.
