A Novel Framework for Improving the Breakdown Point of Robust Regression Algorithms

no code implementations20 May 2023 Zheyi Fan, Szu Hui Ng, Qingpei Hu

Finally, we demonstrate that the breakdown point of CORALS is indeed higher than that of the algorithm from which it is derived.

A model aggregation approach for high-dimensional large-scale optimization

no code implementations16 May 2022 Haowei Wang, Ercong Zhang, Szu Hui Ng, Giulia Pedrielli

In this study, we propose a model aggregation method in the Bayesian optimization (MamBO) algorithm for efficiently solving high-dimensional large-scale optimization problems.

Adjusted Expected Improvement for Cumulative Regret Minimization in Noisy Bayesian Optimization

no code implementations10 May 2022 Shouri Hu, Haowei Wang, Zhongxiang Dai, Bryan Kian Hsiang Low, Szu Hui Ng

To adapt the EI for better performance under cumulative regret, we introduce a novel quantity called the evaluation cost which is compared against the acquisition function, and with this, develop the expected improvement-cost (EIC) algorithm.

Combined Global and Local Search for Optimization with Gaussian Process Models

no code implementations7 Jul 2021 Qun Meng, Songhao Wang, Szu Hui Ng

Based on this AGLGP model, we propose a Combined Global and Local search for Optimization (CGLO) algorithm.
