Researchers have developed new estimators for unbalanced optimal transport, a statistical method that extends classical optimal transport to measures with differing total masses. The study focuses on quadratic costs and Kullback-Leibler marginal penalties, proposing that the target should be a transport-growth pair rather than just a map. The proposed estimators achieve minimax optimal rates, providing a statistical foundation for estimation in this area. AI
