Feature Subset Selection By Estimation Of Distribution Algorithms
نویسنده
چکیده
This paper describes the application of four evolutionary algorithms to the selection of feature subsets for classification problems. Besides of a simple genetic algorithm (GA), the paper considers three estimation of distribution algorithms (EDAs): a compact GA, an extended compact GA, and the Bayesian Optimization Algorithm. The objective is to determine if the EDAs present advantages over the simple GA in terms of accuracy or speed in this problem. The experiments used a Naive Bayes classifier and public-domain and artificial data sets. All the algorithms found feature subsets that resulted in higher accuracies than using all the features. However, in contrast with other studies, we did not find evidence to support or reject the use of EDAs for this problem.

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...
