Feature Subset Selection in Unsupervised Learning via Multiobjective Optimization

by Julia H, Joshua Knowles
"... Abstract: In this paper, the problem of unsupervised feature selection and its formulation as a multiobjective optimization problem are investigated. Two existing multiobjective methods from the literature are revisited and used as the basis for an algorithmic framework, encompassing both wrapper an ..."

Crossover Operators for Multiobjective k-Subset Selection

by Thorsten Meinl, Michael R. Berthold
"... Genetic algorithms are often applied to combinatorial opti-mization problems, the most popular one probably being the traveling salesperson problem. In contrast to permutations used for TSP, the selection of a subset from a larger set has so far gained surprisingly little interest. One intriguing ex ..."

Feature selection in clustering problems

by Volker Roth, Tilman Lange - In Advances in Neural Information Processing Systems 16 , 2004
"... A novel approach to combining clustering and feature selection is presented. It implements a wrapper strategy for feature selection, in the sense that the features are directly selected by optimizing the discriminative power of the used partitioning algorithm. On the technical side, we present an ef ..."

search spaces like in the case of feature selection. Moreover, feature selection is an inherently multi-objective problem with many competing objectives involving size, predictive power and redundancy of the feature subset under consideration. Hence, Multi-Objective Genetic Algorithms (MOGAs) are a

Optimization to carry out the search for (quasi) optimal subsets of features considering possible conflicting importance criteria. This work presents an application of Multi-objective Genetic Algorithms to the Feature Selection problem, combining different criteria measuring the importance of the subsets

An Evolutionary Multi-Objective Local Selection Algorithm for Customer Targeting

by Yongseog Kim, W. Nick Street - in: Proc. of Congress on Evolutionary Computation (CEC-01), accepted
"... In an increasingly competitive marketplace, one of the most interesting and challenging problems is how to identify and profile customers who are most likely to be interested in new products or services. At the same time, minimizing the number of variables used in the prediction task is important wi ..."

Evolutionary algorithms are considered effective in solving multiobjective problems because of their inherent parallelism. We use ELSA, an evolutionary local selection

Feature Subset Selection using Ant Colony Optimization

by Ahmed Al-ani - International Journal of Computational Intelligence , 2006
"... Abstract—Feature selection is an important step in many pattern classification problems. It is applied to select a subset of features, from a much larger set, such that the selected subset is sufficient to perform the classification task. Due to its importance, the problem of feature selection has b ..."
