Calibration is crucial for understanding and trusting reported probabilities in AI models. Recent studies have shown that enforcing calibration at the level of individual predictors can improve ensemble accuracy and calibration, particularly in mixture-of-experts (MoE) models. However, the conditions under which calibration helps MoE are not well understood. This work aims to fill this gap by studying how MoE models behave under distribution shift, with a focus on the interaction between routing mechanisms and expert calibration. The researchers analyze the effects of distribution shift on MoE models and explore the role of calibration in improving their performance. The study provides insights into the importance of calibration in MoE models and sheds light on the conditions under which it can be beneficial.
