| • | The same visible
sequence can be produced by |

| many different
hidden sequences |
|||||||||||||||
| – | This
is just like the fact that the same datapoint |
||||||||||||||
| could
have been produced by many different |
|||||||||||||||
| Gaussians
when we are doing clustering. |
|||||||||||||||
| – | But
there are exponentially many possible |
||||||||||||||
| hidden
sequences. |

seems hard to figure out |
