New theory unifies statistical and algorithmic approaches to inverse optimal transport

A new paper introduces Sinkhorn linearization and a spectral proxy to unify the statistical and algorithmic theories of feature-parameterized inverse optimal transport. The research develops a core bound that drives four theorems and one observation, addressing identifiability, sparsistency, well-posedness, and convergence of estimators. The findings include theoretical guarantees for recovering true parameters and convergence rates for gradient descent, with an assessment of misspecification effects. AI

IMPACT Provides theoretical foundations that could advance machine learning algorithms and statistical modeling.
