A research site about moving probability distributions through the geometry of optimal transport.

Landing page captured for the 2026-09-19 issue.
For
Researchers and builders working with graphs, distributions, or time series
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.
