Maxwell-Boltzmann Distribution Scottish physicist James Clerk Maxwell developed his kinetic theory of gases in 1859. Maxwell determined the distribution of velocities among the molecules of a gas. Maxwell's finding was later generalized in 1871 by a German physicist, Ludwig Boltzmann, to express the distribution of energies among the molecules.

Each visible unit (node) is connected to each hidden unit, but there are no intra-visible or intra-hidden connections. Figure 1.6 illustrates this. RBMs are explored in [11, 4].
