ICE-SEARCH: A Language Model-Driven Feature Selection Approach

no code implementations28 Feb 2024 Tianze Yang, Tianyi Yang, Shaoshan Liu, Fuyuan Lvu, Xue Liu

This study unveils the In-Context Evolutionary Search (ICE-SEARCH) method, the first work that melds language models (LMs) with evolutionary algorithms for feature selection (FS) tasks and demonstrates its effectiveness in Medical Predictive Analytics (MPA) applications.

Practical Anomaly Detection over Multivariate Monitoring Metrics for Online Services

no code implementations19 Aug 2023 Jinyang Liu, Tianyi Yang, Zhuangbin Chen, Yuxin Su, Cong Feng, Zengyin Yang, Michael R. Lyu

As modern software systems continue to grow in terms of complexity and volume, anomaly detection on multivariate monitoring metrics, which profile systems' health status, becomes more and more critical and challenging.

Heterogeneous Anomaly Detection for Software Systems via Semi-supervised Cross-modal Attention

2 code implementations14 Feb 2023 Cheryl Lee, Tianyi Yang, Zhuangbin Chen, Yuxin Su, Yongqiang Yang, Michael R. Lyu

Our study demonstrates that logs and metrics can manifest system anomalies collaboratively and complementarily, and neither of them only is sufficient.

Schrödinger PCA: On the Duality between Principal Component Analysis and Schrödinger Equation

no code implementations8 Jun 2020 Ziming Liu, Sitian Qian, Yi-Xuan Wang, Yuxuan Yan, Tianyi Yang

Counterintuitively, by drawing the connection between PCA and Schr\"odinger equation, we can not only attack the undersampling challenge but also compute in an efficient and decoupled way with the proposed algorithm called Schr\"odinger PCA.
