The experiments are conducted on the Wishart planted ensemble with N = 20 and α = 0.05. a The Kullback–Leibler (KL) divergence DKL(qθ∣∣p) between the variational distribution qθ and the Boltzmann distribution p. The inset shows the DKL(qθ∣∣p) when the inverse temperature β is small. b The relative errors (Rel. Err) of the variational free energy Fq relative to the exact free energy F. The inset shows the relative errors when β is small.
