In today world of internet, it is important to feedback the users based on what they demand. Moreover, one of the important tasks in data mining is classification. Today, there are several classification techniques in order to solve the classification problems like Genetic Algorithm, Decision Tree, Bayesian and others. In this article, it is attempted to classify researchers to “Expert” and “No...
Background & objective: One of the common purposes of medical research is Determination of effective factors on the occurrence of event. Due to the interaction of risk factors regression models, discriminant analysis and classification procedures used. Uses of these models require making the assumption which in the medical data isn’t usually established. Therefore, alternative methods must be u...

the prediction of liquefaction potential of soil due to an earthquake is an essential task in civil engineering. the decision tree is a tree structure consisting of internal and terminal nodes which process the data to ultimately yield a classification. c4.5 is a known algorithm widely used to design decision trees. in this algorithm, a pruning process is carried out to solve the problem of the...
Railway infrastructures are among the most important national assets of countries. Most of the annual budget of infrastructure managers are spent on repairing, improving and maintaining railways. The best repair method should consider all economic and technical aspects of the problem. In recent years, data analysis of maintenance records has contributed significantly for minimizing the costs. B...
According to the forensic statistics, in Iran, 26 percent of those killed in traffic accidents are motorcyclists in recent years. Thus, it is necessary to investigate the causes of motorcycle accidents because of the high number of motorcyclist casualties. Motorcyclists' dangerous behaviors are among the causes of events that are discussed in this study. Traffic signs have the important role of...

We consider the problem of classifying an unknown observation into one of several populations using tree-structured allocation rules. Although many parametric classification procedures are robust to certain assumption violations, there is need for discriminant procedures that can be utilized regardless of the group-conditional distributions that underlie the model. The treestructured allocation...
Introduction: Inadequate dialysis for patients' kidneys as a mortality risk necessitates the presence of a pattern to assist staff in dialysate part to provide the proper services for dialysis patients and also the proper management of their treatment. Since the role of buffer type in the adequacy of dialysis is determinative, the present study is aimed at determining hemodialysis buffer type. ...
