Figure 3. Feature importance averaged over 5 fold cross-validation.
The resultant DT selected by the SC procedure is presented as a machine diagram in Fig. 4. Each splitting node of the DT provides a specific question that has a yes/no answer, and two branches. The terminal nodes provide the predictive probabilities of alert, whose values range between 0.0 and 1.0.

node01 X04 < 1847.05, then node03, otherwise node45 node03 X04 < 1459.91, then node06, otherwise node28 node06 X05 < -281.95, then node15, otherwise node07 node07 X03 < 1713.61, then node08, otherwise node12
