New methods combine simulation and real-world data for improved AI model training

Researchers have developed new strategies for training surrogate models by integrating data from multiple sources, including simulations and real-world measurements. One approach involves training separate models for each data type and then combining their predictions, while another trains a single model incorporating both data types. These hybrid methods aim to improve predictive accuracy and coverage, and to identify potential issues within existing simulation models, ultimately aiding in system understanding and future development.
