The paper introduces modal calibration for nominal outcomes, distinguishes full/partial/average calibration, demonstrates logical independence of double PIT calibration for discrete outcomes, and generalizes calibration results expressed via functionals of predictive distributions.
Augments the energy score objective for sample-based generative models with a differentiable decision loss that is itself a proper scoring rule, yielding targeted improvements on cost-sensitive regions in synthetic and real tasks.
