Conditional PED-ANOVA: Hyperparameter Importance in Hierarchical & Dynamic Search Spaces
Researchers have developed a new framework called conditional PED-ANOVA (condPED-ANOVA) to accurately estimate hyperparameter importance in complex, conditional search spaces. This method addresses the limitations of previous approaches that could not handle hyperparameters whose presence or domain depends on other settings. Experiments demonstrate that condPED-ANOVA provides meaningful and reliable importance measures, unlike naive adaptations of existing estimators which can yield misleading results in conditional scenarios. The team has also made their code publicly available. AI
