Advanced: Speeding up an enumerated string search in a data mining application

This week, I am going to cover a technique that I used to speed up a data mining application that had a search through enumerated strings looking for all the matches. Using this technique of substituting numeric values for the strings, I was able to see a twenty fold speed increase.
Also, my colleague Scott thought that people interested in this video should check out categorical arrays in the statistics toolbox.
