Outlier detection is an important area of machine learning, and I believe this book is a valuable resource to understand the field itself and to understand how to effectively conduct outlier detection projects. It goes through the purposes for outlier detection, the common tools, how they work, their limitations, practical considerations to produce meaningful results, methods to combine detectors, and methods to evaluate results. The book also puts an emphasis on interpretability, allowing users to understand why some items may be considered statistically more unusual than other items.
