    Fault diagnosis on material handling system using feature selection and data mining techniques
    (ELSEVIER SCI LTD, 2014) YILDIZ, KAZIM; Demetgul, M.; Yildiz, K.; Taskin, S.; Tansel, I. N.; Yazicioglu, O.
    The material handling systems are one of the key components of the most modern manufacturing systems. The sensory signals of material handling systems are nonlinear and have unique characteristics. It is very difficult to encode and classify these signals by using multipurpose methods. In this study, performances of multiple generic methods were studied for the diagnostic of the pneumatic systems of the material handling systems. Diffusion Map (DM), Local Linear Embedding (LLE) and AutoEncoder (AE) algorithms were used for future extraction. Encoded signals were classified by using the Gustafson-Kessel (GK) and k-medoids algorithms. The accuracy of the estimations was better than 90% when the LLE was used with GK algorithm.
