Active Learning for Deep Gaussian Process Surrogates

1 code implementation15 Dec 2020 Annie Sauer, Robert B. Gramacy, David Higdon

Deep Gaussian processes (DGPs) are increasingly popular as predictive models in machine learning (ML) for their non-stationary flexibility and ability to cope with abrupt regime changes in training data.
