摘要:

本文提出了一种新的广义二维粒子群特征选择学习方法。该方法的核心思想是通过扩展速度的维度,将子集基数的信息包含到学习框架中。2D学习框架保留了原始PSO的所有关键功能,尽管有额外的学习维度。PSO的大多数流行的变体可以很容易地适应这个二维学习框架的特征选择问题。考虑到几个基准数据和两个归纳算法:朴素贝叶斯和k-最近邻的学习方法的有效性进行了评估。与GA、ACO和其他5种PSO算法的时间复杂度分析结果表明,所提出的二维学习方法在较短的运行时间内获得了基数相对较小的特征子集和较好的分类性能.

英文摘要:

This paper proposes a new generalized two dimensional learning approach for particle swarm based feature selection. The core idea of the proposed approach is to include the information about the subset cardinality into the learning framework by extending the dimension of the velocity. The 2D-learning framework retains all the key features of the original PSO, despite the extra learning dimension. Most of the popular variants of PSO can easily be adapted into this 2D learning framework for feature selection problems. The efficacy of the proposed learning approach has been evaluated considering several benchmark data and two induction algorithms: Naive-Bayes and k-Nearest Neighbor. The results of the comparative investigation including the time-complexity analysis with GA, ACO and five other PSO variants illustrate that the proposed 2D learning approach gives feature subset with relatively smaller cardinality and better classification performance with shorter run times.
