AFAIK, mert picks some points at random indeed, but it picks the exact same points from run to run (on the same data). In other words, rerunning it on the same models (same data + same training sequence) will provide the same results. > But, yes, in general, changing any aspect of the system, > including the alignment heuristic used, will result in different > weights.
