摘要
电子商务信用风险评估是建设信用体系的重要环节。在企业电子商务数据采集存在缺失值的情况下,本文比较了BP神经网络、支持向量机、决策树、极限学习机以及对应的集成模型在含缺失值预测样本的鲁棒性。实证数据分析结果显示,极限学习机及其集成模型在上述情况下优于其他模型。
E-commerce credit risk assessment is an important part of the construction of credit system.This paper compares the robustness of the integrated models corresponding to BP neural network,support vector machine,decision tree and extreme learning machine in the case of missing value of enterprise e-commerce data.The analysis results of empirical data show that extreme learning machine and its integrated model are better than other models.
