Summary
In this chapter, we discussed the theory behind the iSAX index and how the SAX representation is related to the iSAX index. We also learned how to manually create an iSAX index given a time series and the required parameters. Additionally, we developed some handy command-line utilities that support iSAX indexes. We now understand the necessary theory behind iSAX and are ready to apply it.
The next chapter uses this chapter as its foundation in order to develop a Python package for computing iSAX indexes.
