Based on a chosen value of \(W\) segments and alphabet size \(A\), each \(N\) size window is transformed into a SAX word. An example of this process is seen in Figure \ref{fig:SAXWord}. This example shows two daily profiles which are converted to the SAX words, acba and abba. The SAX word is useful from an interpretation point of view in that each letter corresponds consistently to a subsequence of data from the daily profile. For example, the first letter explains the relative performance for the hours of midnight to 6:00 AM. Therefore if the size of \(A\) is set to 3, a SAX word whose first letter is \(a\) would have low, \(b\) would indicate average, and \(c\) would correspond to high consumption. Larger sizes of \(A\) would create SAX words with a more diverse range of characters and would capture more resolution magnitude-wise.
