Mining manufacturing data using genetic algorithm-based feature set decomposition

Data mining methods can be used for discovering interesting patterns in manufacturing databases. These patterns can be used to improve manufacturing processes. However, data accumulated in manufacturing plants usually suffers from the "Curse of Dimensionality", i.e. relatively small number of records comparing to large number of input features. As a result, conventional data mining methods may be inaccurate in these cases. This paper presents a new feature set decomposition approach that is based on genetic algorithm. For this purpose a new encoding schema is proposed and its properties are discussed. Moreover we examine the effectiveness of using a Vapnik-Chervonenkis dimension bound for evaluating the fitness function of multiple oblivious trees classifiers. The new algorithm was tested on various realworld manufacturing datasets. The obtained results have been compared to other methods, indicating the superiority of the proposed algorithm.
