Support Vectors
   - Support vectors are lines that are used to separate categories.
 
   - Usually, if there is one there are many lines that can separate
       two categories.
 
   - What is the best one?
 
   
 
   - You want to use the line that is furthest from both categories.  Why?
   
 
   - The support vectors are the lines that are on the edge of one
       category.
 
   - You use the support vectors to calculate the best line,
       the maximum margin separator.
