Multi-fidelity surrogate-based methods play an important role in modern engineering design applications. aiming to improve model accuracy while reducing computational cost. One of the widely adopted approaches is the calibration-based method. which calibrates the low-fidelity model through a discrepancy model between low-fidelity and high-fidelity models. https://www.inmuebleslasmercedes.com/product-category/frothing-cups/
