Course Work Discussion
   - Could you use this week's lab to build an MLP that solves the problem?
   
 
   - Remember, the course work is a two fold test.
 
   - If it wasn't trained, what result would it get?
 
   - Once you've got a Euclidean categoriser, an MLP is not a bad way
       to go.
 
   - Only one pair of students (using convolution) did about as well as
       categorising by distance.  Why?
 
   - How would you manage backprop if you want to implement an MLP for
       the coursework?
