Surrogate models are essential for emulating and quantifying uncertainty on expensive computer simulators for complex systems.
A new LOL-GP model is proposed, focusing on local transfer learning Gaussian Process for effective surrogate training on a target system using information from related source systems.
The LOL-GP incorporates a latent regularization model that identifies regions for beneficial transfer and areas where transfer should be avoided to mitigate the risk of negative transfer.
Numerical experiments and an application for jet turbine design demonstrate the improved surrogate performance of the LOL-GP over existing methods.
