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

Moreover, for privacy reasons, Microsoft claims that Recall will be able to detect sensitive information, and won’t save or store those snapshots. Concerns “We’ve updated Recall to detect sensitive information like credit card details, passwords, and personal identification numbers. When detect...
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 ...
Qtip:For help interpreting fraud detection fields (bot detection, duplicate submissions, etc), seeFraud Detection. Randomization Data Qtip:For step-by-step instructions on how to include randomization data in your response data export, seeExporting Randomized Data. ...
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...
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 ...

We compare performance of six single classifiers trained on German credit dataset, an imbalanced dataset of 1000 instances with binary-valued dependent variable. To improve the performance, we consider resampling the dataset and ensembling the classifiers. The benchmarks are taken from the best perform...
