arXiv:2606.08935v1 Announce Type: new Abstract: Representation-based time-series anomaly detection algorithms significantly outperform other methods on diverse anomaly detection tasks. However, we notice that they suffer from a major limitation in our evaluation - their learned embeddings are often amplitude-agnostic. Losing amplitude information can degrade performance on amplitude related anomalies, and this failure is prevalent across all existing representation-based methods. To address aforementioned issues, we propose a new anomaly scoring scheme named PAI. PAI consists of two complement
The continuous drive for more accurate and robust AI models across diverse applications necessitates addressing current limitations in established anomaly detection techniques, as AI systems become more prevalent in real-time monitoring.
Improved anomaly detection, particularly in time-series data, is critical for maintaining operational integrity in complex AI-driven systems within various sectors, preventing failures and enhancing reliability.
The proposed PAI method directly addresses a known weakness in representation-based time-series anomaly detection, potentially leading to more accurate and reliable identification of amplitude-related anomalies.
