This book provides a readable and elegant presentation of the principles
of anomaly detection, providing an easy introduction for newcomers to
the field. A large number of algorithms are succinctly described, along
with a presentation of their strengths and weaknesses.
The authors also cover algorithms that address different kinds of
problems of interest with single and multiple time series data and
multi-dimensional data. New ensemble anomaly detection algorithms are
described, utilizing the benefits provided by diverse algorithms, each
of which work well on some kinds of data.
With advancements in technology and the extensive use of the internet as
a medium for communications and commerce, there has been a tremendous
increase in the threats faced by individuals and organizations from
attackers and criminal entities. Variations in the observable behaviors
of individuals (from others and from their own past behaviors) have been
found to be useful in predicting potential problems of various kinds.
Hence computer scientists and statisticians have been conducting
research on automatically identifying anomalies in large datasets.
This book will primarily target practitioners and researchers who are
newcomers to the area of modern anomaly detection techniques.
Advanced-level students in computer science will also find this book
helpful with their studies.
