- Worth noticing
- The demo visualizes barycentric coding by moving a point around a triangle of graph distributions.
Field notes
The site connects optimal-transport theory to graph-based probability and time-series analysis, with research materials organized under papers, talks, projects, and a blog. Its featured browser interaction uses barycentric coding: a point moves around a triangle while the associated distribution changes across a graph. The homepage also links to preprints, GitHub, and packages associated with change-point detection and graph measures.
