Extend or create new loading CSV functions to change string columns to numerical (e.g. Sonar dataset stores class as "R" (rock) or "M" (mine), but should be stored as 0 and 1 (not 1 and 2!).
Currently we have a "temp" version of the file in the /data/ directory. Let's wrap up this logic in a function instead so we can easily load other datasets.
