Comparison of predicted output and measured values of SFCSo as to illustrate, NN structures performance Root Mean squared error (RMSE) and Mean AbsolutePercentage Error (MAPE) were used. They are formulated as follows:where, n is the number of samples and x i and y i are the values of the i th samples in x and y,respectively.(2)(3)where, f i is the predicted value, y i is the actual value, n is the number of pattern.In this context, in order to compare network performance of BP, Mean Absolute Percentage Error(MAPE) and RMSE (Root Mean Squared Error) were used. Analysis results are shown in the Table 2.(4)25
