【摘要】 消费者信用评估是金融与银行界研究的重要内容,最近的研究显示统计学习理论(SLT)方法在信用评估中有优势。本文在信用评估中应用了一种新的方法——支持向量机方法(SVM),该方法属于机器学习理论发展的最新阶段,具有专门针对有限样本、算法复杂度与样本维数无关等优点。使用真实的信用卡数据实证结果表明,本方法具有较好的预测能力,在与国内某商业银行现有信用卡个人信用评估方法的对比研究中,该方法具有明显的优势。更多还原

【Abstract】 Credit assessment has attracted lots of researchers in financial and banking industry. Recent studies have shown (that) Statistic Learning Theory(SLT) methods are competitive to statistical methods for credit assessment. This article (applies) support vector machines(SVM), a relatively new machine learning technique, to the credit assessment problem for (better) explanatory power. The structure of SVM has many computation advantages, such as special direction at a finite (sample) and irrelevance between the complexity of algorithm and the sample dimension. A real credit card data experiment (shows) that SVM method has outstanding assessment ability. Compared with the method that is currently used by a major (Chinese) bank, the SVM method has a great potential superiority in predicting accuracy.更多还原
