摘要:
为了提高单支持向量机(SVM)回归模型的泛化能力,引入遗传算法(GA)用以搜索SVM的"低偏差区域",给出了一种基于GA的SVM异构集成方法。用此方法对十个典型的数据集进行回归预测,并与单SVM回归结果和Bagging集成回归结果进行了比较,表明这种异构集成方法有较好的泛化能力。将这种方法应用于感兴趣的四个渭河陕西段水质参数的遥感反演,取得了更为精确的预测结果。实验表明,对小样本情况,基于GA的SVM异构集成方法能在付出合理时间花销的条件下,使单SVM的泛化能力得到有效提升
Abstract:
To improve the generalization ability of a single SVM regression model,a heterogeneous ensemble approach of SVMs is proposed by employing GA to search low bias region.Ten representative data sets were regressed,comparing with the single SVM regression and
