If I have a single peak in the posterior with a likelihood of 1 should I not expect that sampling from the posterior and maximising the posterior likelihood return the same value? Following that, if the average description length obtained by sampling from the posterior is different I must have had other partitions with non-zero probabilities contributing which contradicts the entropy of zero. Am I making a logical mistake/missing something here?
There could be several of such isolated peaks of the posterior, where the MCMC gets trapped. -- Tiago de Paula Peixoto <tiago@skewed.de>
