摘要:

欺诈检测是一个重要的主题,适用于各种企业,如银行和金融部门,保险,政府机构,执法部门等。近年来,欺诈行为显著增加,使欺诈检测成为一个重要的研究课题。欺诈检测的主要挑战之一是获取欺诈样本,这是一项复杂且具有挑战性的任务。为了应对这一挑战,我们采用单类分类方法,如SVDD,它不需要欺诈样本进行训练。此外,我们提出了我们的算法REDBSCAN,这是DBSCAN的扩展,以减少样本的数量,并选择那些保持数据的形状。实验结果表明,该方法在检测性能和速度上都有较大的提高。

英文摘要:

Fraud detection is an important topic that applies to various enterprises such as banking and financial sectors, insurance, government agencies, law enforcement, and more. Fraud attempts have been risen remarkably in current years, shaping fraud detection an essential topic for research. One of the main challenges in fraud detection is acquiring fraud samples which is a complex and challenging task. In order to deal with this challenge, we apply one-class classification methods such as SVDD which does not need the fraud samples for training. Also, we present our algorithm REDBSCAN which is an extension of DBSCAN to reduce the number of samples and select those that keep the shape of data. The results obtained by the implementation of the proposed method indicated that the fraud detection process was improved in both performance and speed.
