Hi,
I got iteration 3:
teration 1, lambda = (0.5 0.5), ppl = 4.91204
iteration 2, lambda = (0.514374 0.485626), ppl = 4.908
iteration 3, lambda = (0.528604 0.471396), ppl = 4.90404
It seems that the final ppl will not less than that from word-based
trigram (4.80), in other words, there is no minimum between the two end
points. The other end (class) is 5.08, not too bad. I'll wait until the
iteration stops.
Good day,
Hongqin
