| • | We assume that
the data was generated from a |
|||||||||||
| number of
different classes. The aim is to cluster |
||||||||||||
| data from the
same class together. |
||||||||||||
| – | How
do we decide the number of classes? |
|||||||||||
| – | Why
not put each datapoint into a separate |
|||||||||||
| class? |

| • | What is the
objective function that is optimized |
|||||||||||
| by sensible
clusterings? |
