This page is devoted to show the supplementary materials for the paper entitled "Detecting Pneumatic Failures on Temporary Immersion Bioreactors" published in Lecture Notes in Computer Science, pp. 293-302, 2016.
In this paper, we study the use of contrast pattern-based classifiers, designed for class imbalance problems, for creating an understandable and accurate model for detecting pneumatic failures on temporary immersion bioreactors. Our experiments over eight real-world databases show that a decision tree ensemble obtains significantly better AUC results than other tested classifiers.

Statistical Tests

CD diagrams with a statistical comparison of the classification results and statistical results using Friedman's test (as a non-parametric test) and Shaffer static procedure (as a post-hoc procedure) [1]. The post hoc comparisons contain α = 0.05, α = 0.10, and adjusted p-values. ->
