Graph anomaly detection plays a crucial role in identifying exceptional instances in graph data that deviate significantly from the majority.

Contrastive Learning Graph Anomaly Detection

Fixed-time safe tracking control of uncertain high-order nonlinear pure-feedback systems via unified transformation functions

no code implementations30 Apr 2023 Chaoqun Guo, Jiangping Hu, Jiasheng Hao, Sergej Celikovsky, Xiaoming Hu

Combined with the proposed unified transformation function and the FDSC technique, an adaptive fixed-time control strategy is proposed to guarantee the fixed-time tracking.
