Means of mitigating distribution shift include rolling backtests on recent data, introducing exogenous variables, and online calibration of model outputs; the fundamental measure is to establish monitoring that triggers human review or model updates when the distribution of forecast residuals changes significantly.

UnverifiedThe key insight of this study is that when the likelihood function derived from the data model is known and differentiable, guided diffusion modeling can be used to sample the predictive distribution.77% similarUnverifiedDomain Adaptation shows that a medium-sized model thoroughly fine-tuned on target distribution data can often outperform a large general-purpose model that has not seen such data on test sets from that distribution.76% similarUnverifiedThe robustness of a distribution essentially depends on how its tail behavior is modeled, and replacing the Gaussian distribution with a heavy-tailed distribution can improve a model's stability against outliers.73% similarVerifiedDistribution shift refers to the systematic difference between the statistical distribution of data seen during model training and the distribution of data in the actual deployment environment.73% similarUnverified将分散损失与知识蒸馏结合，用大模型的嵌入分布特性作为分散约束的参考目标，是一个潜在的研究方向73% similar
