Entropic optimal transport beyond product reference couplings: the Gaussian case on Euclidean space
Paul Freulon, Nikitas Georgakis, Victor Panaretos
The Optimal Transport (OT) problem with squared Euclidean cost consists in finding a coupling between two input measures that maximizes correlation. Consequently, the optimal coupl…

CytOpT: Optimal Transport with Domain Adaptation for Interpreting Flow Cytometry data
Paul Freulon, Jérémie Bigot, Boris P. Hejblum
The automated analysis of flow cytometry measurements is an active research field. We introduce a new algorithm, referred to as CytOpT, using regularized optimal transport to direc…
