Abstract :
The author comments that Zhang (see ibid., vol.5, no.12, p.1662-65, 1996) attempts to establish the convergence of a mean field iteration for an Ising Markov random field (MRF) for large values of the hyperparameter value /spl beta/ is not correct for the function T/sub /spl delta//(u) defined. The convergence of the mean field iteration remains an open question for large /spl beta/.
