Trajectory-Based Multi-Objective Hyperparameter Optimization for Model Retraining

no code implementations24 May 2024 Wenyu Wang, Zheyi Fan, Szu Hui Ng

Training machine learning models inherently involves a resource-intensive and noisy iterative learning procedure that allows epoch-wise monitoring of the model performance.

Minimizing UCB: a Better Local Search Strategy in Local Bayesian Optimization

no code implementations24 May 2024 Zheyi Fan, Wenyu Wang, Szu Hui Ng, Qingpei Hu

Through this insight, we propose a new local Bayesian optimization algorithm, MinUCB, which replaces the gradient descent step with minimizing UCB in GIBO.

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 Bayesian Robust Regression Method for Corrupted Data Reconstruction

no code implementations24 Dec 2022 Zheyi Fan, Zhaohui Li, Jingyan Wang, Dennis K. J. Lin, Xiao Xiong, Qingpei Hu

Because of the widespread existence of noise and data corruption, recovering the true regression parameters with a certain proportion of corrupted response variables is an essential task.
