Feature Selection in Data Mining

An Evaluation of Sampling on Filter-Based Feature Selection Methods

Feature selection and data sampling are two of the most important data preprocessing activities in the practice of data mining. Feature selection is used to remove less important features from the training data set, while data sampling is an effective means for dealing with the class imbalance problem. While the impacts of feature selection and class imbalance have been frequently investigated ...

Feature Selection: An Ever Evolving Frontier in Data Mining

The rapid advance of computer technologies in data processing, collection, and storage has provided unparalleled opportunities to expand capabilities in production, services, communications, and research. However, immense quantities of high-dimensional data renew the challenges to the state-of-the-art data mining techniques. Feature selection is an effective technique for dimension reduction an...

Feature Selection for High Dimensional Data: An Evolutionary Filter Approach

Problem statement: Feature selection is a task of crucial importance for the application of machine learning in various domains. In addition, the recent increase of data dimensionality poses a severe challenge to many existing feature selection approaches with respect to efficiency and effectiveness. As an example, genetic algorithm is an effective search algorithm that lends itself directly to...

An Incremental Approach to MSE-Based Feature Selection

Feature selection plays an important role in classification systems. Using classifier error rate as the evaluation function, feature selection is integrated with incremental training. A neural network classifier is implemented with an incremental training approach to detect and discard irrelevant features. By learning attributes one after another, our classifier can find directly the attributes...
