• 
The distribution
generated by this



infinite
directed net with replicated



weights is the
equilibrium distribution


for a compatible
pair of conditional



distributions:
p(vh) and p(hv) that



are both defined
by W




– 
A
topdown pass of the directed



net
is exactly equivalent to letting



a
Restricted Boltzmann Machine



settle
to equilibrium.




– 
So
this infinite directed net



defines
the same distribution as



an
RBM.
