Fraud detection is a knowledge-intensive activity. The main AI techniques used for fraud detection include: Data mining to classify, cluster, and segment the data and automatically find associations and rules in the data that may signify interesting patterns, including those related to fraud.
The Isolation Forest algorithm provides a robust solution for anomaly detection, particularly in domains like fraud detection where anomalies are rare and challenging to identify. However, its reliance on hyperparameters and sensitivity to imbalanced data necessitate careful tuning and complementary techniques for optimal results. [6] [8]
It is widely used in the financial sector, especially by accounting firms, to help detect fraud. In 2022, PricewaterhouseCoopers reported that fraud has impacted 46% of all businesses in the world. [1] The shift from working in person to working from home has brought increased access to data.
The paper is the outcome of a research project (launched in 2021) by the Wikimedia Foundation's research team with external collaborators, alongside a public API hosted by WMF. Like the "Edisum" model for model for automatically generating Wikipedia edit summaries that we covered in our last issue , its approach seems to have been shaped and ...

In Denmark, scientific misconduct is defined as "intention[al] negligence leading to fabrication of the scientific message or a false credit or emphasis given to a scientist", and in Sweden as "intention[al] distortion of the research process by fabrication of data, text, hypothesis, or methods from another researcher's manuscript form or ...
Cybercriminals have created large language models focused on fraud, including WormGPT and FraudGPT. [164] A 2023 study showed that generative AI can be vulnerable to jailbreaks, reverse psychology and prompt injection attacks, enabling attackers to obtain help with harmful requests, such as for crafting social engineering and phishing attacks ...
