Researchers have developed PaAno, a novel lightweight model for time-series anomaly detection designed for efficiency and accuracy. The model utilizes a multiscale feature-extraction backbone with convolutional kernels and cross-scale attention to capture hierarchical temporal characteristics. It also incorporates a cross-variable fusion attention module to model inter-variable correlations and a pretext task based on temporal patch-window sorting to enhance feature discrimination. Experiments on the TSB-AD benchmark show PaAno achieving state-of-the-art detection accuracy on both univariate and multivariate tasks with favorable computational efficiency for real-time inference.
