Credit risk is the primary source of risk to financial institutions. Support vector machine (SVM) is a good classifier to solve binary classification problem. The learning results of SVM possess stronger robustness. We adjust these penalty parameters to achieve better generalization performances with using grid-search method in our application. In this(More)
