QSAR concepts are chemical compound (system), activity/property, descriptor, (Q SAR model, prediction (training, validation, testing) and QsarDB concepts Compound, Property, Descriptor, Model, Prediction respectively.
Calculations of model prediction error on the training data indicated little or no improvement in model performance when more predictor variables are included, i.e. models with all predictor variables (full), or built stepwise (step).
Based on the above foundation above, it can be implemented as follows to realize the SVR: data scaling, model training, and model prediction.
Figures 15 and 16 compare the average absolute errors between the correlation (Glaso 1985) and the GRNN model predictions for the training and testing data sets, respectively.
It is plausible that the lack of fit of model predictions between different training sets in Chitwan is due to different forest populations used in their sampling.

Further analysis, excluding the existing outbreak focussed in Guinea from the dataset used to train the model (prediction maps available on request), still resulted in prediction of high suitability in this region, with the presumed index village located within 5km of an at-risk pixel.
R2 (coefficient of determination) values between the actual (Bottom ash/Coal burned) ratios and the model predictions were 0.988 for the training set and 0.984 for the testing set.
Parameters in the neural network model were trained until the model predictions of salinity matched well with the observations.
In figure 4b, we compare the residuals of the fadeouts on population size between the observed data, initial gravity model predictions, adjusted gravity model predictions for high train use coastal towns, and adjusted gravity model predictions for all coastal towns.
Forecasting model training and prediction is done for daily intervals in high order Hilbert space, derived from the anonymized and aggregated mobile network activity in Trentino.
