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.

Concluding all that we have learned so far

Time series are everywhere! But time series tend to get larger and larger as we collect more data, more frequently. Therefore, we need ways to process and search large time series faster and faster in order to make useful deductions from the data.

The iSAX index is here to help you search your time series data fast. I hope that this book has given you the necessary tools and knowledge to begin working with time series and subsequences, as well as the iSAX index in Python. However, the knowledge and the presented techniques are easily transferable to other programming languages, including but not limited to Swift, Java, C, C++, Ruby, Kotlin, Go, Rust, and JavaScript.

We believe that we have provided the right amount of knowledge about time series indexing using the right amount of theory and practice so you can successfully work with time series and develop iSAX indexes.

The next section presents improved versions of iSAX.
