Özet

Advances in medicine enable the production of large amounts of data and the discovery of alternative treatment methods using this data, and valuable information. By using data mining and machine learning methods, it is possible to analyze big data and extract important information from these data. The biggest challenge in information extraction is the presence of many unnecessary variables that reduce the performance of machine learning methods and disadvantage in terms of computation time and complexity. In this study, binary version of the PSO-GWO optimization algorithm, which is a hybrid optimization method, is applied to medical data to extract these unnecessary variables from the model and the accuracy comparisons are made by using different classifiers. Two data sets are used for comparisons. In both data sets, instead of using all the variables, classification using the variables found with the hybrid approach gives higher accuracy values. As a result, using a reduced number of features instead of all features increases the performance of the classifier, avoiding the use of many unnecessary variables, provides advantages in terms of computation time.
