Hello,

I have a few questions on running MMSAPT within EMS. I am refering to
the doc here : http://www.statmt.org/moses/?n=Advanced.Incremental
and to the sections of the config.basic file of EMS.

1) the doc says
initial training run EMS as usual but use modified version of Giza++ and
add training-options = "-final-alignment-model hmm"
Does this mean that we cannot use FastAlign for initial training ? or
does FastAlign support hmm ?
also can the -final-alignment-model hmm parameter be in the same as line
as other training-options ? (-sort-compress -cores ....)

2) do we need to comment the
alignment-symmetrization-method=grow-diag-final-and line ?

3) what is the difference between : ("for use with interactive
post-editing")

mmsapt = "pfwd=g pbwd=g smooth=0.01 rare=0 prov=0 sample=1000 workers=1"
binarize-all = $moses-script-dir/training/binarize-model.perl
and
mmsapt = "pfwd=g pbwd=g smooth=0 rare=1 prov=1 sample=1000 workers=1"
binarize-all = $moses-script-dir/training/binarize-model.perl

4) then there is a section in the config file for which I find no
documentation but seems related
use of baseline alignment model (incremental training)
baseline=68
then 8 lines of parameters

5) in the "Updates" section of the doc (adding new data) I see nothing
related with EMS.
Does this mean that at this time there is no actual incremental training
within EMS and this part has to be done manually ?

Thanks for your help,

Vincent
