Expected improvement ei criterion

WebThe expected improvement (EI) criterion is considered as a stan-dard method for this purpose [20]. EI makes use of the internal uncertainty estimate provided by Kriging. The EI of a candidate so-lution increases if the predicted value or the estimated uncertainty of the model rises.
