Calculating MPdist using iSAX
In this section, we are going to discuss our views and ideas regarding using iSAX indexes to approximately compute MPdist.
We know that iSAX keeps together subsequences with the same SAX representation. As before, our feeling is that it is more likely to find the nearest neighbor of a subsequence from a given time series in the subsequences with the same SAX representation from another time series.
The next section is about putting our thoughts into practice.
