I have read the Levenshtein article but am confused as to it's usfulness in code training.

Please explaine ?

Matthew

What article? Be explicit please.

The Levenshtein distance is the number of changes required to transform one morse character to the other. Hence h and 5 has a small one and 5 and T is a large one.

This means that you can easier hear the difference between T and 5 than between h and 5.

This means that when you have difficulties in detecting the difference of your characterset during your learning proces, you are better off with exercising the set t and h than 5 and h.

Still much better is not to bother abt Levenshtein, but just to exercise till you copy a small set of 2 characters 90% solid, and after the add a third character.

In the scoring portion of the course,click "Levenshtein Score" and you will get Wikipedia's explaination.

The accuracy is calculated by two different methods. First, comparing group by group, splitting them up at every whitespace-character. Then by the Levenshtein distance. In case a space between two groups is omitted somewhere, the first checking algorithm fails. That's why the Levenshtein distance is used as a fallback method of determining the error rate.

In every case, the better of the two calculated accuracy values is used for the statistics.
