Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

Abstract: In recent years, graph neural network has been widely used. Attention mechanism is introduced into the graph neural network to make it more applicable. Both GAT and AGNN prove that attention ...

Abstract: Semi-supervised learning can effectively utilize limited labeled data and large amounts of unlabeled data to achieve fault diagnosis on process industries. This paper proposes a novel cosine ...
