Look At Me, No Replay! SurpriseNet: Anomaly Detection Inspired Class Incremental Learning

1 code implementation30 Oct 2023 Anton Lee, Yaqian Zhang, Heitor Murilo Gomes, Albert Bifet, Bernhard Pfahringer

A common solution to both problems is "replay," where a limited buffer of past instances is utilized to learn cross-task knowledge and mitigate catastrophic interference.

A simple but strong baseline for online continual learning: Repeated Augmented Rehearsal

1 code implementation28 Sep 2022 Yaqian Zhang, Bernhard Pfahringer, Eibe Frank, Albert Bifet, Nick Jin Sean Lim, Yunzhe Jia

Despite its strong empirical performance, rehearsal methods still suffer from a poor approximation of the loss landscape of past data with memory samples.

Continual Learning Reinforcement Learning (RL)

A non-invasive fault location method for modular multilevel converters under light load conditions

no code implementations16 Aug 2022 Yaqian Zhang, Yi Zhang, Frede Blaabjerg, Jianzhong Zhang

The proposed approach of injecting the second-order circulating current will rebuild the bipolar arm current of the MMC and enlarge the capacitor voltage deviations between the healthy and faulty SMs.

Closed-loop Control for Online Continual Learning

no code implementations29 Sep 2021 Yaqian Zhang, Eibe Frank, Bernhard Pfahringer, Albert Bifet, Nick Jin Sean Lim, Alvin Jia

To address the non-stationarity in the continual learning environment, we employ a Q function with task-specific and task-shared components to support fast adaptation.

A Graph-Based Semi-Supervised k Nearest-Neighbor Method for Nonlinear Manifold Distributed Data Classification

no code implementations3 Jun 2016 Enmei Tu, Yaqian Zhang, Lin Zhu, Jie Yang, Nikola Kasabov

In this paper, we propose a new graph-based $k$NN algorithm which can effectively handle both Gaussian distributed data and nonlinear manifold distributed data.
