The role of temporal feature extraction and bagging of MLP neural networks for solving the WCCI 2008 Ford Classification Challenge

Abstract: This paper presents an approach for solving WCCI 2008's Ford Classification Challenge Problem. The solution is based on the creation of new input variables through temporal feature extraction and on the combination via bagging of an ensemble of 30 multi-layer perceptrons trained on sets divided by multiple random sampling of the labeled data. Signal power, signal to noise ratio and signal frequency were some of the meaningful features extracted for improving the system's performance. The data sampling strategy… Show more

“…In this case, unfortunately, the organizers of the competition did not publish the classification methods used by the contributors. To the best of our knowledge, the only contributor that published a description of the method used was Paulo Adeodato (Adeodato et al, 2009), which ranked seventh in the competition. The strategy he and his colleagues followed for classifying the data consisted of an initial phase of feature extraction, where more than a hundred features were extracted for each sequence, and a classification phase, where an ensemble of 30 multilayer perceptrons was used.…”
