Nts, even the RF model that presented a case withTheIPE of12.66 (37.40 vs. a effectively squared correlation coefficient for the Figure 2). Once an ANN model presents 38.39, overestimated the real value) (see training phase (0.937) with an RMSET value of 0.745 C that corresponded having a MAPET worth of three.95 . ANN models present a similar behaviour involving them, that is definitely, ANN1 and ANN2 present great adjustments for the instruction phase with r2 values of 0.937 and 0.934 and equivalent root mean square errors (0.745 C and 0.717 C with MAPET values of three.95 and 3.07 ), respectively. The SVM model presents related adjustments to these reported by the ANNMathematics 2021, 9,10 ofmodels (while with a slight improvement in the RMSE and MAPE values). As soon as once more, the RF model presented the ideal adjustment for the training phase with an r2 T of 0.972 and an RMSET of 0.467 C that corresponded using a MAPET of 1.99 . In Figure three, it could be observed that the ANN2 model and SVM model presented, for the training phase, two points away from the line with slope a single (best suitable of the figure). For the ANN2 model, these two points (28.09 C and 27.91 C) present predicted values of 24.79 C and 24.99 C, respectively (IPE values of -11.76 and -10.47 ), that is, the model underestimated the actual values. For the SVM model, within the coaching phase, precisely the same two points present undesirable predictions with IPE values of -20.03 and -18.93 (each circumstances underestimated.) In the ANN1 model, 1 of these two points had been also far in the line with slope one (28.09 C vs. the predicted Mathematics 2021, 9, x FOR PEER Review 11 of 15 value of 24.59 C).Figure three.

The black line corresponds and ANN2 , random forest model (RF) and assistance vector machine model (SVM) created. The black line corresponds to to the line with slope one particular. the line with slope a single.All of the models developed within this study to decide 18O, salinity, and temperature/potential temperature worked rather effectively, showing Methyl jasmonate Purity & Documentation acceptable errors beneath 8.00 . The low percentage of error and the very good square correlation coefficient values shown by the models to predict salinity and temperature/potential temperature seemed to indicate that there was a higher correlation involving the input variables as well as the variables to become predicted. This reality didn’t seem so marked inside the case from the models to predict 18O, exactly where,Mathematics 2021, 9,11 ofIn the validation phase, all models present excellent benefits in accordance with the squared correlation coefficient that incorporates values among 0.926 and 0.972 with RMSEV values inside the variety 0.452.757 C (Table two). It can be stated that an error below one particular degree may well be acceptable. Inside the SVM model (Figure 3) could be observed the presence of 3 points away in the line with slope a single that present IPE values of -14.13 , 11.31 and 19.60 . The same three points can also be noticed away in the line with slope a single within the ANN1 model (IPE values amongst -12.94 and 15.13 ). For the querying phase, the ANN models present the worse outcomes. This can be clearly noticed for the ANN2 model exactly where the RMSE elevated to 0.777 C that corresponds to a MAPE of 3.34 . The prediction is slightly enhanced by the ANN1 model (0.699 C). Onc.
