GLTF-FEDformer: an adaptive time-frequency fusion method for multivariate time series anomaly detection enhanced by prediction error embedding

Multivariate time series are widespread in scenarios such as industrial IoT, smart manufacturing, energy systems, and medical monitoring. Their anomalous behaviors often involve complex patterns like long-range dependency changes, local dynamic shifts, transient spectral perturbations, and variable-association mismat...
