Modern finance involves crunching more data that any single human can efficiently and effectively process. Sophisticated machine learning models and applications have dominated the high-end fintech industry for decades. Now that extraordinarily powerful AI technologies are readily available to everyone, you can take advantage of deep learning, graph analytics, and large language models (LLMs) to create your own custom finance applications.

Financial AI needs to navigate rapidly changing conditions, process incredibly complex data, make split-second decisions and, of course, do it all within the restrictions of regulatory compliance. Author Taehun Kim has spent over a decade building AI systems that perform on the front lines of the finance industry.

In Financial AI in Practice you’ll learn how to:

• Build end-to-end AI pipelines for credit scoring and fraud detection
• Design hybrid strategies combining ML models and LLM-driven insights
• Expose complex fraud using graph analytics and network detection
• Architect secure, compliant generative AI with RAG techniques
• Navigate AI business strategy, ROI, and stakeholder alignment

About the book

Financial AI in Practice shows you how to deliver financial AI solutions that are more than just a few deployed algorithms. You’ll learn to build a complete, compliant application using the kind of messy, imperfect data you'll encounter in industry. The book introduces around four complete, production-minded systems that handle the core tasks of credit, fraud, investment, and operational efficiency. You’ll build an end-to-end pipeline that assesses credit risk, use supervised, unsupervised, and graph-based models to detect fraud, and combine a quantitative model with LLM-powered news analyses for a hybrid investment strategy. As you build, you’ll master Taehun’s simple-but-powerful 4-Layer Framework, a mental model you can apply to any AI project in finance.
