Contrastive autoencoder for anomaly detection in multivariate time series
Zhou, Hao; Yu, Ke; Zhang, Xuan; Wu, Guanlin; Yazidi, Anis (Peer reviewed; Journal article, 2022)With the proliferation of the Internet of Things, a large amount of multivariate time series (MTS) data is being produced daily by industrial systems, corresponding in many cases to life-critical tasks. The recent anomaly ... -
Developing ductile and isotropic Ti alloy with tailored composition for laser powder bed fusion
Wang, Leyun; Song, Zhe; Zhang, Xuan; Park, Jun-Sang; Almer, Jonathan; Zhu, Gaoming; Chen, Yiwen; Li, Quan; Zeng, Xiaoqin; Li, Yanjun (Peer reviewed; Journal article, 2022)Laser powder bed fusion (LPBF) is an advanced technology to create metallic components with complex geometry. Ti-6Al-4V (Ti64) is one of the most frequently used materials for LPBF. The intrinsic high cooling rates and ... -
The Hierarchical Discrete Pursuit Learning Automaton: A Novel Scheme With Fast Convergence and Epsilon-Optimality
Omslandseter, Rebekka Olsson; Jiao, Lei; Zhang, Xuan; Yazidi, Anis; Oommen, John (Peer reviewed; Journal article, 2022)Since the early 1960s, the paradigm of learning automata (LA) has experienced abundant interest. Arguably, it has also served as the foundation for the phenomenon and field of reinforcement learning (RL). Over the decades, ...
