Notice that, by default Optuna tries to minimize the objective function, since we use native log loss function to maximize the Random Forrest Classifier, we add another negative sign in in front of the cross-validation scores. 4. Run the Optuna trials to find the best hyper parameter configura...

We have implemented a decision tree classifier for RFE. Based on the aggregate difference between the features space, we have set the ranking of features from the most important to the least important. Table 2 Different combinations of optimizers and loss functions. Full size table Feature ...
