结果发现,frauder和其out neibour的node features存在相对于normal 用户更大的差异,这个其实也make sense吧,物以类聚,人以群分,正常人填写的紧急联系人可能是和自己比较亲近的人,关系好的同事,朋友之类的,收入,年龄啊之类的可能差不多,而frauder的紧急联系人可能就不太一样了,毕竟你要去构造一群frauder 账户,...
while obtaining human predictions for training and evaluation is costly. Financial fraud detection is a high-stakes setting where algorithms and human experts often work in tandem; however, there are no publicly available datasets for L2D concerning this important application of human-AI teaming. To ...

Amazon-Fraud is a multi-relational graph dataset built upon the Amazon review dataset, which can be used in evaluating graph-based node classification, fraud detection, and anomaly detection models. Dataset Statistics | # Nodes | %Fraud Nodes (Clas
Here’s the problem: most machine learning algorithms are optimists. They aim for high accuracy by favoring the majority class, completely missing the subtle patterns in the underrepresented group. Take fraud detection—if only 0.1% of transactions are fraudulent, a model might lazily label everythi...
For the Source Detection task we have used the K-fold cross-validation and the Few-shot partitions on the Clip-cropped instances. Finally, to compare the SIDTD dataset on the later task to more real data we have evaluate the performance of the selected deep learning models on the private ...
