VerifiedSimpson's paradox refers to the phenomenon in which a trend observed in grouped data may completely reverse when the data are aggregated.71% similarUnverifiedThe paper finds that the predictive mean and variance undergo phase transitions at different scales and that the two are not synchronized.70% similarUnverifiedWhen covariates are imbalanced or skewed, some observations become high-leverage points that exert a disproportionate influence on the regression coefficients, so that even with the same N and p, out-of-sample predictive performance can differ greatly.70% similarUnverifiedTRACER achieves the lowest values on both group-level conversion rate error and semantic trajectory distance metrics, and generalizes to out-of-distribution scenarios.69% similarUnverifiedWhen all sampled outputs in a group are incorrect, the group-relative advantage collapses to zero, causing the model to receive no effective gradient feedback in high-uncertainty scenarios.69% similar
