The article titled "Spatio-Temporal Attention Graph Neural Network for Remaining Useful Life Prediction" by Zhixin Huang, Yujiang He, and Bernhard Sick proposes the application of Spatio-Temporal Attention Graph Neural Network for remaining useful life prediction in industrial systems. It addresses the limitations of existing models by combining graph neural networks and convolutional temporal neural networks. It shows state-of-the-art results with uniform normalization and a 27% increase in performance with cluster normalization in datasets with multiple operating conditions.
