A Clustering-Based Framework for Identifying Suspicious Trading Patterns in Capital Market
TL;DR
Suspicious trading patterns in capital markets pose significant risks, prompting the development of a clustering-based framework for detection. This framework utilizes unsupervised learning techniques to analyze trading data and identify anomalies.
✦ Why It Matters
Implement this clustering framework in trading systems to enhance the detection of suspicious activities and protect market integrity.
Key Takeaways
- Utilize unsupervised learning for fraud detection in trading.
- Analyze transaction data from 2012 to 2024 for insights.
- Focus on identifying spoofing and other fraudulent activities.
- Validate model performance using clustering metrics like Silhouette Score.
How It Works
The framework employs K-Means++ clustering to group financial transactions based on their characteristics, allowing for the identification of outliers that may indicate fraudulent behavior. By setting heuristic thresholds, the model categorizes trades into various types of suspicious activities, enhancing the detection process.
