The Brier score can be decomposed into three parts—reliability (calibration), resolution (discrimination), and uncertainty—which helps locate the source of problems.

UnverifiedThe Brier score is the mean squared error between predicted probabilities and actual outcomes; lower is better, and it penalizes both wrong direction and overconfidence.71% similarUnverifiedIn the paper's formal setting, the compound risk is defined as the excess Brier score relative to the true mapping, averaged over all problems.67% similarUnverifiedThe BROJA scheme, proposed by Bertschinger, Rauh, Olbrich, Jost, and Ay, defines redundant information via a constrained optimization problem by searching, among all joint distributions satisfying specific marginal constraints, for the distribution that maximizes redundant information.67% similarUnverifiedKalman-type methods assume that both state and observation errors follow Gaussian distributions and perform well in linear systems, but their accuracy degrades when faced with high-dimensional non-Gaussian problems.66% similarUnverifiedPrior research has shown that when each pairwise source–target variable joint distribution follows a Gaussian distribution, the BROJA optimization problem can be reduced to a finite-dimensional numerical optimization problem.66% similar
