From: Prediction of Filamentous Sludge Bulking using a State-based Gaussian Processes Regression Model

Comparisons of Gaussian processes for micro sludge bulking diagnosis with different covariance functions (covSE: Squared-Exp kernel; covNN: Neural Network kernel; covMatérniso: Matérniso kernel; covAdd: Addictive kernel) and other models (RBF: Radical Basis Function; DeepNN: Deep Neural Network; PLS: Partial Squares Least; More details about the Kernel can see Supplementary Information).
