    The distribution
    generated by this 
     | 
   
   
     | 
    infinite DAG with
    replicated 
     | 
     | 
   
   
     | 
    weights is the
    equilibrium 
     | 
     | 
   
   
     | 
    distribution for
    a compatible pair 
     | 
     | 
   
   
     | 
    of conditional
    distributions: p(v|h) 
     | 
     | 
   
   
     | 
    and p(h|v). 
     |

    – | 
    An
    ancestral pass of the DAG 
     | 
     | 
   
   
     | 
    is
    exactly equivalent to letting 
     | 
     | 
   
   
     | 
    a
    Restricted Boltzmann 
     |

    Machine

    So
    this infinite DAG defines 
     | 
     | 
   
   
     | 
    the
    same distribution as an 
     | 
     | 
   
   
     | 
    RBM.
