The Impact of Hyper-Parameter Tuning for Landscape-Aware Performance Regression and Algorithm Selection

no code implementations19 Apr 2021 Anja Jankovic, Gorjan Popovski, Tome Eftimov, Carola Doerr

By comparing a total number of 30 different models, each coupled with 2 complementary regression strategies, we derive guidelines for the tuning of the regression models and provide general recommendations for a more systematic use of classical machine learning models in landscape-aware algorithm selection.
