A Study on Feature Selection Using Machine Learning Techniques

Feature selection has become an emerging research area in the field of pattern recognition and machine learning. It is one of the most important processes in Knowledge Discovery. The data set contains irrelevant, redundant and noisy data, which can be preprocessed using feature selection technique. Through feature selection technique the relevant features are identified for the mining process. Feature selection is one of the factors to classify the data without any misclassification and address the performance of the model. In this study, an attempt is made to review the different feature selection techniques in machine learning scheme.
