Hi list,
It seems that currently for both, pro and kbmira, optimization of BLEU
is hardwired into the code. I managed to add my custom metric to mert,
but would like to experiment with it and sparse features, too.

I see custom metrics is on a TODO list in the mert folder, is someone
working on custom metrics for sparse features?
Are pro and/or kbmira in principle compatible with this "sufficient
statistics per sentence" approach as it is done for mert? Any pointers
how I could best attack this?

Best,
Marcin

Hello all



when I run moses EMS, in the tuning step, it gives this exception:

Exception: moses/FF/Factory.cpp:235 in void
Moses::FeatureRegistry::Construct(const string&, const string&) threw
UnknownFeatureException because `i == registry_.end()'.
Feature name IRSTLM is not registered.
Exit code: 1
Failed to run moses with the config
/opt/working/ems/tuning/moses.filtered.ini.1 at
/opt/tools/mosesdecoder/scripts/training/mert-moses.pl line 1271.
cp: cannot stat '/opt/working/ems/tuning/tmp.1/moses.ini': No such file or
directory


I will be thankful if you could help me to solve this problem.

Regards

amir

Hi,

I have been tackling with one compiling failure as follows, would you
please tell me how to work around?

$HOME = /home/scott/

$ cd /home/scott/tools
$ cd mosesdecoder
$ ./bjam -j2 --with-irstlm=/home/scott/tools/irstlm
--with-giza=/home/scott/tools/giza-pp
--with-boost=/home/scott/tools/boost_1_55_0 --debug-configuration -d2
> build.log

====== BEGIN OUTPUT ======
Running 1 test case...
moses/LM/BackwardTest.cpp(162): error in "ProbingAll":
difference{100%} between static_cast<double>(TransformLMScore( 0.0
)){0} and static_cast<double>(ngramScore){1.3724476843890443e-07}
exceeds 0.01%

*** 1 failure detected in test suite "BackwardTest"

EXIT STATUS: 201
====== END OUTPUT ======
