| A very surprising fact |
|
|
|
|
|
| • | Everything that
one weight needs to know about |
|||
| the other weights
and the data is contained in |
||||
| the difference of
two correlations. |

|
|
|
|
|
| Expected
value of |

| product
of states at |

| thermal
equilibrium |
||||
| when the
training |

| vector
is clamped |

| on
the visible units |
