Estimating Compressive Strength of High Performance Concrete with Gaussian Process Regression Model

Algorithm 1

Grid search procedure for GPR hyperparameter determination.

Establishing Subset1, Subset2

Establishing ParSet

PM =      // Performance matrix

For    // N _P = number of hyper parameters in ParameterSet

     For

        Train GPR model with Subset1

        GPR model prediction with Subset2

        PM(i,j) = RMSE of Subset2

        // RMSE denotes the Root Mean Squared Error
