Abstract

Over the past few decades numerous learning algorithms have been proposed to extract knowledge from data The majority of these algorithms have been developed with the assumption that training sets can denote populations When the training sets contain only a few properties of their populations the algorithms may extract minimal and/or biased knowledge for decision makers This study develops a systematic procedure based on fuzzy theories to create new training sets by rebuilding the possible sample distributions where the procedure contains new functions that estimate domains and a sample generating method In this study two real cases of a leading company in the thin film transistor liquid crystal display (TFT-LCD) industry are examined Two learning algorithms a back-propagation neural network and support vector regression are employed for modeling and two sample generation approaches bootstrap aggregating (bagging) and the synthetic minority over-sampling technique (SMOTE) are employed to compare the accuracy of the models The results indicate that the proposed method outperforms bagging and the SMOTE with the greatest amount of statistical support
