UnverifiedThe Brier score formula is BS = (1/N)Σ(f_i - o_i)^2, measuring the mean squared error between predicted probabilities and actual outcomes, where a lower score indicates greater accuracy and a perfect prediction scores 0.78% similarUnverifiedThe core property of a strictly proper scoring rule is that the expected score is maximized if and only if the forecaster reports the probability they truly believe, with common examples including log-likelihood loss and the Brier score.73% similarVerifiedExpected Calibration Error (ECE) bins prediction samples by confidence level, computes the weighted average of the difference between predicted confidence and actual accuracy within each bin, and ideally approaches 0.69% similarUnverifiedThe endpoint metric used in the evaluation is the difference of 'model minus uniform control group', where a positive value represents performing worse than the control.67% similarUnverified评估基准测试质量的关键指标是假阳性率和假阴性率，理想基准应将两者控制在较低水平67% similar
