ABSTRACT
ABSTRACT: Recently, big data analytics has proceeded in various field according to the development of information technology and analysis tools. However, there are few examples of big data analytics in the field of railway mechanical systems, because the vehicle performance are evaluated by motion analysis or experiment under the specific conditions. By contrast, condition monitoring systems are introduced in the railway systems, and these monitoring systems enable the big data to be accumulated during commercial operation. In this paper, the big data of running records in railway systems are analyzed by using naive bayes classifier, one of the method of big data analytics, and individualities of railway vehicles are identified.
