Resumo: | |||||||||||||
Consider a network with k nodes that may fail along its operation. Furthermore
assume that it is impossible to check all nodes whenever a failure
occurs. Motivated by this scenario, we propose a method that uses supervised
learning to generate rankings of the most likely nodes responsible for
the failure. The proposed method is a meta-classifier that is able to use any
kind of classifier internally, where the model generated by the meta-classifier
is a composition of those generated by the internal classifiers. Each internal
model is trained with a subset of the data created from the elimination of
instances whose classes were already put in the ranking. Metrics derived
from Accuracy, Precision and Recall were proposed and used to evaluate
this method. Using a public data set, we verified that the training and classification
times of the meta-classifier were greater than those of a simple
classifier. However it reaches better results in some cases, as with the decision
trees, that exceeds the benchmark accuracy for a margin greater than
5 percent.
