Fight Fraud with Machine Learning

Fraudsters adapt daily; your defenses must evolve even faster. Stop revenue leaks before they cripple your business. Move beyond rules and guesswork toward data-driven certainty. Turn raw transaction streams into clear, actionable fraud signals. Master proven Python workflows used by top fintech security teams. Guard customers, profits, and reputation with confidence.  Rule-based foundations: Build quick wins and create reliable baselines for later models.  Classical algorithms: Use logistic regression and decision trees to flag card and transaction anomalies.  Ensemble power: Apply random forests and gradient boosted trees for higher recall with fewer false positives.  Deep learning: Deploy neural networks, vision transformers, and graph CNNs to catch modern, multi-channel attacks.  Real datasets: Follow complete, annotated Python notebooks ready for adaptation to your production stack.  Evaluation playbook: Measure accuracy, precision, recall, and cost impact to justify every security investment.  Fight Fraud with Machine Learning by Ashish Ranjan Jha is a guide that combines academic research with battle-tested industry practice. Jha draws on a decade at Oracle, Sony, Revolut, and Tractable to deliver clear, reproducible solutions.  The book progresses from simple rules to cutting-edge deep-learning approaches, each chapter adding complexity and capability. Step-by-step labs, code listings, and annotated diagrams let readers learn by doing. Case studies span credit cards, KYC, and social bots, illustrating breadth and depth.  Finish the final chapter ready to deploy robust models that slash fraud losses, impress auditors, and protect customer trust. Your new skill set will translate directly into safer products and stronger career prospects.  Ideal for data scientists, ML engineers, and fraud-prevention product managers comfortable with Python.
