Michael T. Gastner, Vivien Seguy, Pratyush More
Cartograms are maps that rescale geographic regions (e.g., countries, districts) such that their areas are proportional to quantitative demographic data (e.g., population size, gro…
Blind Source Separation with Optimal Transport Non-negative Matrix Factorization
Antoine Rolet, Vivien Seguy, Mathieu Blondel +1
Optimal transport as a loss for machine learning optimization problems has recently gained a lot of attention. Building upon recent advances in computational optimal transport, we…
Log-PCA versus Geodesic PCA of histograms in the Wasserstein space
