Parameters Selection of SVM Based on Extended APSO Algorithm

摘要: 支持向量机是最近才兴起的一种分类工具，它广泛用于控制领域，但是其预测精度受到了其参数选取的影响。使用活跃目标点改进粒子群优化算法,利用活跃目标点粒子群算法搜索支持向量机的最优参数组合。对比仿真实验表明：活跃目标点粒子群算法可以正确支持向量机的参数，能够进行较为准确的分类。

Abstract: Support Vector Machine (SVM), a new mathematic modeling tool, has been widely used in many industry applications. The good generalization ability and estimation accuracy are impacted by parameters selection of SVM. Particle Swarm Optimization is improved by using active target. The active target particle swarm optimization was proposed to search the optimal combination of SVM parameters. Simulations show that active target particle swarm optimization is an effective way to search the SVM parameters and has good performance in classification.
