Low-Rank Representations Meets Deep Unfolding: A Generalized and Interpretable Network for Hyperspectral Anomaly Detection

no code implementations23 Feb 2024 Chenyu Li, Bing Zhang, Danfeng Hong, Jing Yao, Jocelyn Chanussot

These factors also limit the performance of the well-known low-rank representation (LRR) models in terms of robustness on the separation of background and target features and the reliance on manual parameter selection.

Koopa: Learning Non-stationary Time Series Dynamics with Koopman Predictors

2 code implementations NeurIPS 2023 Yong liu, Chenyu Li, Jianmin Wang, Mingsheng Long

While previous models suffer from complicated series variations induced by changing temporal distribution, we tackle non-stationary time series with modern Koopman theory that fundamentally considers the underlying time-variant dynamics.

Experimenting with an Evaluation Framework for Imbalanced Data Learning (EFIDL)

no code implementations26 Jan 2023 Chenyu Li, Xia Jiang

We compared the traditional data augmentation evaluation methods with our proposed cross-validation evaluation framework Results Using traditional data augmentation evaluation meta hods will give a false impression of improving the performance.
