We present a new framework for uncertainty quantification via information bottleneck(IB-UQ) in scientific machine learning tasks, including deep neural regression and neural operator learning. IB-UQ can provide uncertainty estimates in the label prediction by explicitly modeling the representation variables. Moreover, IB-UQ can be trained with noisy data and provide accurate predictions with reliable uncertainty estimates on unseen data. We also present the physics-informed version of IB-UQ for PDE-related problems.The capability of the proposed IB-UQ framework is demonstrated with numerical examples.
