A Review of Feature Selection Methods for Classification Problem
نویسندگان
چکیده
The Classification are carried out using various feature selection technique. The feature selection methods allows the classification to be carried out more accurately and efficiently. Feature selection is one of the leading trends in the research work going on. There are various feature selection methods which are used along with the classification methods. According to the application the most appropriate feature selection method is selection for selection the feature. The selected feature is then supplied to the classifier to carry out the classification of data. Here we study 6 different Feature selection method which are Document Frequency (DF), Mutual Information (MI), Information Gain (IG), CHI Square Statistics, and Bi – Normal Separation. These methods are used separately for the text classification or a combination of methods are used. Index Terms Feature Selection, Classification, Mutual Information, Information gain, CHI Square Statistics, Bi – Normal Separation, Text Classification. ________________________________________________________________________________________________________

Feature Selection (FS) is an important pre-processing step in machine learning and data mining. All the traditional feature selection methods assume that the entire feature space is available from the beginning. However, online streaming features (OSF) are an integral part of many real-world applications. In OSF, the number of training examples is fixed while the number of features grows with t...
