Researchers have introduced Stochastic Attention, a novel method to enhance the reliability of scientific foundation models. This technique modifies existing Transformer architectures by introducing randomness during inference, enabling the generation of predictive ensembles without the need for retraining. A calibration objective is proposed to tune a concentration parameter, allowing the model to match its stochastic outputs with target predictions efficiently. Evaluations on weather forecasting and time-series tasks demonstrated that Stochastic Attention provides superior calibration and sharper prediction intervals compared to existing methods, with minimal post-hoc tuning.
