GeneXproTools Environment

Evaluating the Model
 
GeneXproTools 4.0 allows you to evaluate the accuracy of your models in the training set while they are still evolving. In the Run Panel, during a run not only the fitness but also the R-square or Classification Accuracy of the best-of-generation model are plotted in a chart so that you can stop the learning process whenever you see fit. During evolution, you can also see how well the evolving models are fitting your data by observing the Curve Fitting plot (or Target/Model plot in Classification and Logic Synthesis problems).

And after a run, still in the Run Panel, the fitness and R-square or Classification Accuracy of the best-of-run model obtained on the testing set are also shown, giving you also a quick evaluation of the generalizing capabilities of your model.

Then, in the Results Panel, you can further evaluate the performance of your models both on the training and testing sets by comparing the output of your model with the target using both a spreadsheet and a curve fitting plot.

In addition, while accessing your models visually in the Results Panel you can also check the results obtained for a wide set of statistical functions both for the training and testing sets. You can save these statistical evaluations of your models and keep them in the Report Panel for future reference.

Thus, for Function Finding and Time Series Prediction problems, the values for the mean squared error, root mean squared error, mean absolute error, relative squared error, root relative squared error, relative absolute error, R-square, and correlation coefficient can be immediately accessed without leaving the GeneXproTools modeling environment.

And for Classification and Logic Synthesis problems, the values for the classification error, classification accuracy, confusion matrix (true positives, true negatives, false positives, and false negatives), sensitivity, specificity, positive predictive value, negative predictive value, mean squared error, root mean squared error, mean absolute error, relative squared error, root relative squared error, relative absolute error, R-square, and correlation coefficient can also be immediately evaluated without leaving the GeneXproTools modeling environment.
