is it possible you can make your moses.ini file available for us to see? do you know if the same problem occurs if you use the command line moses, rather than mosesserver? Hieu Hoang Researcher New York University, Abu Dhabi http://www.hoang.co.uk/hieu On 21 July 2015 at 18:07, Barry Haddow

[Moses-support] training or tuning ?

2015-07-21 Thread Vincent Nguyen
thanks for your replies. I have done the full EMS with no errors. BLEU seems fine. the EMS was dnoe with the WMT12 parallel data. From here what should I do for real assessment. I have real texts (human translation) should they be used for training or for tuning ? second question : is there

Hi Barry, Thanks for the quick response. I added the switch -threads 18 to the command to raise moses server. The slowness issue persists but in a different form. Most requests return right away, even under heavy load, but some requests (about 5%) take far longer - about 15-20 seconds. Perhaps

Hi Oren Does your host have 18 threads available? It could also be that xmlrpc-c is limiting the number of connections - this can now be configured: https://github.com/moses-smt/mosesdecoder/commit/b3baade7f022edbcea2969679a40616683f63523 Slowdowns in Moses are often caused by disk access

Hello Jian, NPLM reports the log-likelihood of the whole training set, and the number is plausible. assuming you have a minibatch size of 1000, your training set perplexity is exp(1.38122e+08/52853/1000)=13.64 you probably want to measure perplexity on a held-out development set though,
