Expected Improvement versus Predicted Value in Surrogate-Based Optimization

1 code implementation9 Jan 2020 Frederik Rehbach, Martin Zaefferer, Boris Naujoks, Thomas Bartz-Beielstein

Few results from the literature show evidence, that under certain conditions, expected improvement may perform worse than something as simple as the predicted value of the surrogate model.
