Time Series Indexing

By: Mihalis Tsoukalos

Overview of this book

Time series are everywhere, ranging from financial data and system metrics to weather stations and medical records. Being able to access, search, and compare time series data quickly is essential, and this comprehensive guide enables you to do just that by helping you explore SAX representation and the most effective time series index, iSAX. The book begins by teaching you about the implementation of SAX representation in Python as well as the iSAX index, along with the required theory sourced from academic research papers. The chapters are filled with figures and plots to help you follow the presented topics and understand key concepts easily. But what makes this book really great is that it contains the right amount of knowledge about time series indexing using the right amount of theory and practice so that you can work with time series and develop time series indexes successfully. Additionally, the presented code can be easily ported to any other modern programming language, such as Swift, Java, C, C++, Ruby, Kotlin, Go, Rust, and JavaScript. By the end of this book, you'll have learned how to harness the power of iSAX and SAX representation to efficiently index and analyze time series data and will be equipped to develop your own time series indexes and effectively work with time series data.

Preface

The title of the book you are reading is Time Series Indexing, which should hint at its contents.

The time series index discussed and explored in this book is called iSAX. iSAX is considered one of the best indexes for time series, which is the main reason for choosing it. Besides implementing iSAX and the SAX representation as Python 3 packages, this book shows how to work with time series at the subsequence level and understand the information presented in academic research papers.

But the book does not stop here as it presents Python scripts for getting to know your time series data better and code for visualizing time series data and iSAX indexes to better understand the data as well as the structure of a particular iSAX index.
