摘 要：data assimilation aims to optimally integrate model prediction and observation data to achieve a better estimation and predication for the state variables which are governed by the model. it has been the cornerstone for the modern weather forecast. in this talk, i shall first give a brief overview of data assimilation methodologies and their numerical techniques. i shall then present a scientific machine learning perspective for data assimilation problems and resulting efficient numerical algorithms based on the new perspective.
