AdaST: Adaptive Coupling for Spatial-Temporal Forecasting

Spatial-temporal (ST) forecasting underpins many real-world systems such as traffic, climate, and energy networks. While existing methods implicitly assume strong spatiotemporal coupling, we observe that real-world ST data exhibits distinct coupling regimes, ranging from temporal-dominated and spatial-dominated to stro...

HETCLNN: A Lightweight Intrusion Detection Network with Class-Aware Self-Knowledge Distillation

With the proliferation of edge computing, building efficient NIDS faces challenges related to limited computational resources and class imbalance. To address the issues of high overhead and poor detection of rare attacks in existing models, this paper proposes a lightweight intrusion detection model based on Class-Awar...
