Alignments generated by force_align is different from the original alignment.

Hi,

I followed the steps in issue 33 and saved fwd_params, fwd_err, rev_params and rev_err after running fast_align on the training corpus. Later I compared the alignment results by running fast_align from scratch and running force_align.py with the saved params on that training corpus.

I was expecting fast_align produces exactly the same alignments either from scratch or by force_align, but I got different alignments.

I'm sure I followed the correct steps to run these comparisons, so I'm wondering why the alignments are differnt.

hi,
I ran into the same problem. After reading the code, I found that when the ExportToFile method in ttables.h persists parameters, parameters are filtered by threshold.
It may be that some parameters are filtered out and the results are inconsistent, but I don't know if that's the root cause.

Any updates on this?
