Survey on Feature Selection
This is an incremental survey paper summarizing existing feature selection methods for data mining practitioners.
This paper reviews different feature selection approaches and their relationships with various machine learning algorithms, highlighting how feature selection reduces computational burden and improves accuracy in data mining.
Feature selection plays an important role in the data mining process. It is needed to deal with the excessive number of features, which can become a computational burden on the learning algorithms. It is also necessary, even when computational resources are not scarce, since it improves the accuracy of the machine learning tasks, as we will see in the upcoming sections. In this review, we discuss the different feature selection approaches, and the relation between them and the various machine learning algorithms.
