Complex events (CEs) are important in CPS-IoT applications for high-level decision-making.
Most existing models focus on short-span perception tasks and lack the long-term reasoning required for CE detection.
This case study explores different approaches for CE detection in CPS-IoT, including leveraging large language models, employing neural architectures, and adopting a neurosymbolic approach.
The results show that the state-space model called Mamba outperforms other methods in accuracy and generalization to longer, unseen sensor traces.
