About the book


WHAT'S NEW IN THE 2ND EDITION

Comprehensive and in-depth coverage: The second edition offers a wide range of techniques for anomaly detection. It ensures a well-rounded understanding of the foundational concepts, making it suitable for beginners and seasoned professionals alike. Each chapter builds on the previous one, creating a cohesive and comprehensive learning experience.

Enhanced explanations and visual presentations: We’ve enriched this edition with a wealth of visualizations. These enhancements are designed to clarify complex concepts. You’ll learn not just the ‘how’ but also the ‘why’ behind each method.

Supervised and unsupervised learning techniques: We expand the second edition to cover the advanced machine learning techniques for anomaly detection. On the unsupervised learning part, you will be equipped with a wide range of modern techniques to discover new patterns. On the supervised learning part, you will gain a deeper understanding into grid-search, hyperparameter tuning, regularization, under-sampling and over-sampling techniques. You will use the code examples to build a suite of high-power machine learning models.

200+ data science Q&A: One of the standout features of the second edition is the inclusion of the Q&A sections in each chapter. By working through these questions, you’ll be well-prepared to showcase your expertise and secure your next job opportunity.
