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 0.74% similarUnverifiedThe Spearman correlation coefficient between tool description scores and correct model selection was only 0.04, with almost no statistical association.69% similarVerifiedThe Brier score assesses calibration quality by calculating the square of the difference between the predicted probability and the actual outcome, with a lower score indicating more accurate predictions68% similarUnverifiedThe quality ceiling of weak supervision labels depends on the accuracy of the zero-shot model itself; if the model makes systematic errors, the training set will inherit that bias.67% similarUnverifiedBrier loss is a strictly proper scoring rule, and the true probability is the unique optimal strategy; an uninformative predictor that always outputs 0.5 scores 0.25 on balanced data.66% similar
