Alleviating Search Bias in Bayesian Evolutionary Optimization with Many Heterogeneous Objectives

no code implementations25 Aug 2022 Xilu Wang, Yaochu Jin, Sebastian Schmitt, Markus Olhofer

To this end, we develop a multi-objective Bayesian evolutionary optimization approach to HE-MOPs by exploiting the different data sets on the cheap and expensive objectives in HE-MOPs to alleviate the search bias caused by the heterogeneous evaluation costs for evaluating different objectives.

Transfer Learning Based Co-surrogate Assisted Evolutionary Bi-objective Optimization for Objectives with Non-uniform Evaluation Times

no code implementations30 Aug 2021 Xilu Wang, Yaochu Jin, Sebastian Schmitt, Markus Olhofer

Most existing multiobjetive evolutionary algorithms (MOEAs) implicitly assume that each objective function can be evaluated within the same period of time.

Learning pose variations within shape population by constrained mixtures of factor analyzers

no code implementations7 Jun 2020 Xilu Wang

The segmentation is obtained by components posterior probabilities and the rotations in pose variations are learned by the factor loading matrices.
