English: A graphical representation of a restricted Boltzmann machine. The three blue units represent hidden units, and the four white units represent visible states. In restricted Boltzmann machines there are only connections (dependencies) between hidden and visible units, and none between units of the same type (no hidden-hidden connections nor visible-visible connections).
