Generative adversarial wavelet neural operator: Application to fault detection and isolation of multivariate time series data

no code implementations8 Jan 2024 Jyoti Rani, Tapas Tripura, Hariprasad Kodamana, Souvik Chakraborty

This article proposes a generative adversarial wavelet neural operator (GAWNO) as a novel unsupervised deep learning approach for fault detection and isolation of multivariate time series processes. The GAWNO combines the strengths of wavelet neural operators and generative adversarial networks (GANs) to effectively capture both the temporal distributions and the spatial dependencies among different variables of an underlying system.
