摘要

点击欺诈是一种故意夸大网络广告流量的欺骗行为。对于在网上做广告的企业来说,点击欺诈可能经常发生,导致错误的点击统计和资金损失。这就是为什么许多企业不愿在网站和移动应用程序上为自己的产品做广告的原因。为了安全地营销他们的产品,企业需要一种可靠的技术来检测点击欺诈。在本文中,我们提出了一个堆叠算法来解决这个问题。所提出的方法的前提是将多个学习者结合起来以获得最佳结果。选择了合成少数过采样技术(SMOTE)和欠采样的组合来处理不平衡的数据集。在一级学习器中,有四种有监督的机器学习算法,分别是AdaBoost、随机森林、决策树和逻辑回归。此外,逻辑回归被再次用作二级学习者。为了验证所建议方法的有效性,在中国最大的独立大数据服务平台TalkingData的Kaggle上的公共数据集上进行了比较测试。多个指标,如准确度、F1评分、ROC曲线、损失日志和AUC评分,用于分析预测结果。研究结果表明,叠加方法提高了预测精度,同时保持了较高的稳定性。

Click fraud prediction by stacking algorithm
Click fraud is the sort of deception in which traffic figures for online ads are intentionally inflated. For businesses that advertise online, click fraud may occur often, resulting in erroneous click statistics and lost funds. That is why many businesses are hesitant to advertise their products on websites and mobile apps. To market their products safely, businesses need a reliable technique for detecting click fraud. In this paper we present a stacking algorithm as a solution to this problem. The proposed method’s premise is to combine multiple learners to achieve an optimal result. The Synthetic Minority Oversampling Technique (SMOTE) with a combination of undersampling are chosen to handle the unbalanced dataset. In the first-level learners, there are four supervised Machine Learning algorithms, which are AdaBoost, Random Forest, Decision Tree and Logistic Regression. Moreover, Logistic Regression is used again as a the second-level learner. To verify the efficacy of the suggested approach, comparative tests are carried out on the public dataset available on Kaggle from China’s largest independent big data service platform TalkingData. Multiple indicators, such as Accuracy, F1 Score, ROC curve, Loss Log and AUC Score, are utilized to analyze the prediction outcomes. The findings reveal that the stacking method improves forecast accuracy while also maintaining a high level of stability.
