Researchers have developed a new framework to enhance the reliability of Digital Twins, which are virtual models of physical systems. This framework addresses the issue of 'concept drift,' where the accuracy of the virtual model degrades over time as real-world conditions change. It integrates a novel drift detection system, efficient parameter-efficient continual learning using Low-Rank Adaptation (LoRA), and statistical validation to ensure updates improve predictive performance. Tested on a stochastic linear system and an additive manufacturing process, the framework successfully maintained the accuracy and uncertainty quantification of neural network-based Digital Twins. AI
