arXiv:2602.01359v3 Announce Type: replace Abstract: Although recent studies on time-series anomaly detection have increasingly adopted ever-larger neural network architectures such as transformers and foundation models, they incur high computational costs and memory usage, making them impractical for real-time and resource-constrained scenarios. Moreover, they often fail to demonstrate significant performance gains over simpler methods under rigorous evaluation protocols. In this study, we propose Patch-based representation learning for time-series Anomaly detection (PaAno), a lightweight yet
The proliferation of increasingly complex AI models like transformers has created a pressing need for more efficient and less resource-intensive anomaly detection methods, driven by real-time and edge computing demands.
This development signifies a crucial step towards making advanced AI capabilities more accessible and practical for resource-constrained environments, broadening the application of time-series anomaly detection.
The focus in time-series anomaly detection shifts from exclusively larger, more complex models to lightweight architectures, enabling deployment in environments where previously impractical.

PaAno directly offers a lightweight, patch-based method for time-series anomaly detection, addressing computational and memory constraints.
This could lead to widespread adoption of AI-driven anomaly detection in embedded systems and IoT devices, enhancing predictive maintenance and security at the edge.
The success of lightweight models like PaAno may prompt a broader re-evaluation of optimal model complexity across various AI domains, prioritizing efficiency alongside performance.
