摘要
针对多变量特征选择算法计算效率低、冗余度高的问题,提出一种基于影响力社区检测与蚁群算法的特征选择算法。计算每对数据点之间的相似性,组成无向图,通过人工蚁群优化算法将网络划分为簇;使用社区检测算法对特征进行分类,选择冗余度最小的特征子集;蚁群初始化阶段通过度量特征与类的相关性,初始化信息素。基于人工合成数据集与标准的公开数据集进行实验,实验结果表明,该算法实现了较高的分类准确率、敏感性、特异性,其计算效率处于可接受范围内。
Aiming at the problems of low computational efficiency and high redundancy of multivariate feature selection algorithm,a feature selection algorithm based on influence community detection and ant colony optimization algorithm was proposed.The similarity of each pair of data points was computed to construct a graph,the network was divided into clusters using ant colony optimization algorithm.The community detection was adopted to classify the features,and the feature subset with minimal redundancy was selected.In the initial phase of ant colony,the pheromone was initialized by measuring the correlations between features and clusters.Experimental results based on the synthetic dataset and standard public datasets show that,the proposed algorithm performs good classification accuracy,sensitivity and specificity,at the same time,it realizes reasonable computational efficiency.
