Pick hidden
configurations using a Boltzmann



distribution in
their energies




This
is exactly the posterior distribution over



configurations
given the datavector



Minimize the
expected energy of the chosen



configurations.




Change
the parameters to minimize the energies of



configurations
weighted by their probability of being



picked.



Dont worry
about the changes in the free energy caused


by changes in
the posterior distribution.




We
chose the distribution to minimize free energy.




So
small changes in the distribution have no effect on



the
free energy!
