A Sparse Bayesian Learning for Diagnosis of Nonstationary and Spatially Correlated Faults with Application to Multistation Assembly Systems

no code implementations20 Oct 2023 Jihoon Chung, Zhenyu Kong

This article proposes a novel fault diagnosis method: clustering spatially correlated sparse Bayesian learning (CSSBL), and explicitly demonstrates its applicability in a multistation assembly system that is vulnerable to the above challenges.

On Model Compression for Neural Networks: Framework, Algorithm, and Convergence Guarantee

1 code implementation13 Mar 2023 Chenyang Li, Jihoon Chung, Biao Cai, Haimin Wang, Xianlian Zhou, Bo Shen

This paper focuses on two model compression techniques: low-rank approximation and weight pruning in neural networks, which are very popular nowadays.

Reinforcement Learning-based Defect Mitigation for Quality Assurance of Additive Manufacturing

no code implementations28 Oct 2022 Jihoon Chung, Bo Shen, Andrew Chung Chee Law, Zhenyu, Kong

Since AM typically fabricates a small number of customized products, this paper aims to create an online learning-based strategy to mitigate the new defects in AM process while minimizing the number of samples needed.
