Thanks Chris!
Yes, I've specified the weight I
but also I needed to comment the following lines in the mert script
# foreach my $name (keys %specified_triples) {
# die "Lambdas specified for '$name' ".(@{$specified_triples{$name}}).", b\
ut none needed.\n"
# unless defined($used_triples{$name});
# }
Best,
Marta

Subject: Re: [Moses-support] word lattice + multiple translation tables
optimization problem
I think the issue here has to do with the MERT configuration. When
you use lattice input, the weights on the lattice edges are included
in the translation model as a feature that MERT can optimize. I'm not
familiar with the MERT optimizers that are included with Moses, but it
sounds like it is expecting that you configure a range of possible
values you expect the feature to get. Hope this helps...
