Abstract

Fraudulent insurance claims pose a significant challenge to the sustainability and efficiency of insurance systems, resulting in substantial financial losses and eroding trust between insurers and policyholders. The complexity and volume of modern data make traditional fraud detection methods, such as manual assessments, increasingly ineffective. This study investigates the application of machine learning approaches, including Random Forest and Artificial Neural Networks (ANN), to detect fraud in insurance claims. Using a structured methodology, models were trained on historical claim data and evaluated using metrics such as accuracy, F1-score, recall, and precision. The Random Forest algorithm achieved an accuracy of 94%, while the ANN demonstrated superior performance on controlled datasets. Feature importance analysis identified key predictors, including claim amount and submission frequency, offering actionable insights for fraud prevention strategies. The integration of machine learning into claims management systems provides a scalable, accurate, and cost-effective solution to combating fraud. Future research will focus on testing with larger datasets and exploring hybrid approaches to enhance robustness and adaptability.

Abstract

The digital era presents new opportunities in education, including the integration of artificial intelligence (AI) technologies like ChatGPT. This study explores students' perceptions of using ChatGPT in face-to-face learning through a literature review approach. The analysis draws on various reliable sources, including scientific journals, books, and relevant research reports. The findings suggest that ChatGPT is beneficial for helping students understand materials, complete tasks, and enhance their learning motivation. Additionally, it is considered user-friendly due to its simple interface and quick response times. However, several challenges were identified, including limited digital literacy, the risk of receiving inaccurate information, and the potential misuse of the tool as a shortcut, bypassing deeper engagement with learning materials. The study concludes that ChatGPT holds significant potential to support face-to-face learning, especially when used responsibly under teacher guidance. To maximize its effectiveness, efforts should focus on improving students' digital literacy, establishing clear usage policies, and providing structured guidance during the learning process.
