AI and Machine Learning for E-Commerce Risk Management (Transactions on Computer Systems and Networks)

This book presents a practical, end-to-end approach to risk management in modern e-commerce platforms using machine learning.It covers buyer abuse, seller governance, collusion networks, and payment and credit risk, showing how behavioural, transactional, and network data are translated into actionable risk signals.The book discusses a range of modelling techniques-including tree-based ensembles, sequence and transformer models, graph neural networks, and anomaly detection-focusing on their application under real-world constraints such as class imbalance, latency, adversarial drift, fairness, and regulatory requirements.Extending beyond model development, it addresses deployment, monitoring, governance, and operational assurance, making it relevant to industry practitioners and suitable for advanced courses in applied, industry-focused machine learning.
