Thanks Philipp. I had tried with very tight t-table limits, even with a limit of 1 for both words and pos tags and still it didn't work for this example sequence. This was surprising.
I hope I can avoid shorter phrase-lengths because the task I have in mind would require me to have default phrase lengths at least at the POS tag level. And, would like to avoid using factored model as backoff too because I would like to encourage those translations that have a particular pattern of POS tags. - Sriram On Tue, Apr 16, 2013 at 9:29 PM, Philipp Koehn <[email protected]> wrote: > Hi, > > the translation option expansion of factored models may explode in the > setup that you use above > (there are many possible lemma and pos mappings, and the product of > them is explored during > your first two decoding steps). > > You could remedy this by: > - use shorter phrase lengths > - use tighter t-table limits > - use the factored model only as backoff > > -phi > > On Mon, Apr 15, 2013 at 4:15 PM, Sriram venkatapathy > <[email protected]> wrote: > > > > The decoder (with a factored model) seems to get stuck for certain > > sentences.
