The issue is how to cope with the challenges we face with this ...
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 ...

For example, in a credit card fraud detection dataset, most of the credit card transactions are not fraud and a very few classes are fraud transactions. This leaves us with something like 50:1 ratio between the fraud and non-fraud classes. In this article, I will use the credit card...
Fraud detection with the Paysim financial dataset, Neo4j Graph Data Science, and Neo4j Bloom - neo4j-graph-examples/fraud-detection
In Chapter 2, classification methods will be discussed, which have been extensively implemented for analysing big data in various fields such as customer segmentation, fraud detection, computer vision, speech recognition and medical diagnosis. In brief, classification can be viewed as a labelling proces...
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
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 ...
BentoML makes it efficient to create ML service with multiple ML models, which is often used for combining multiple fraud detection models and getting an aggregated result. With BentoML, users can choose to run models sequentially or in parallel using the Python AsyncIO APIs along with Runners ...
