  • Long Context Translation Models for English-Icelandic translations (22.09)

    ENGLISH: These models are capable of translating between English and Icelandic, in both directions. They are capable of translating several sentences at once and are robust to some input errors such as spelling errors. The models are based on the pretrained mBART25 model (http://hdl.handle.net/20.500.12537/125, https://arxiv.org/abs/2001.08210) and finetuned on bilingual EN-IS data and backtranslated data (including http://hdl.handle.net/20.500.12537/260). The full backtranslation data used includes texts from the following sources: The Icelandic Gigaword Corpus (Without sport) (IGC), The Icelandic Common Crawl Corpus (IC3), Student theses (skemman.is), Greynir News, Wikipedia, Icelandic sagas, Icelandic e-books, Books3, NewsCrawl, Wikipedia, EuroPARL, Reykjavik Grapevine, Iceland Review. The true parallel long context data used is from European Economic Area (EEA) regulations, document-level Icelandic Student Theses Abstracts corpus (IPAC), Stúdentablaðið (university student magazine), The report of the Special Investigation Commision (Rannsóknarnefnd Alþingis), The Bible and Jehovah’s witnesses corpus (JW300). Provided here are model files, a SentencePiece subword-tokenizing model and dictionary files for running the model locally along with scripts for translating sentences on the command line. We refer to the included README for instructions on running inference. ÍSLENSKA: Þessi líkön geta þýtt á milli ensku og íslensku. Líkönin geta þýtt margar málsgreinar í einu og eru þolin gagnvart villum og smávægilegu fráviki í inntaki. Líkönin eru áframþjálfuð þýðingarlíkön sem voru þjálfuð frá mBART25 líkaninu (http://hdl.handle.net/20.500.12537/125, https://arxiv.org/abs/2001.08210). Þjálfunargögin eru samhlíða ensk-íslensk gögn ásamt bakþýðingum (m.a. http://hdl.handle.net/20.500.12537/260). Einmála gögn sem voru bakþýdd og nýtt í þjálfanir eru fengin úr: Risamálheildinni (án íþróttafrétta), Icelandic Common Crawl Corpus (IC3), ritgerðum af skemman.is, fréttum í fréttagrunni Greynis, Wikipedia, íslendingasögurnar, opnar íslenskar rafbækur, Books3, NewsCrawl, Wikipedia, EuroPARL, Reykjavik Grapevine, Iceland Review. Samhliða raungögn eru fengin upp úr European Economic Area (EEA) reglugerðum, samröðuðum útdráttum úr ritgerðum nemenda (IPAC), Stúdentablaðið, Skýrsla Rannsóknarnefndar Alþingis, Biblíunni og samhliða málheild unna úr Varðturninum (JW300). Útgefin eru líkönin sjálf, orðflísunarlíkan og orðabók fyrir flísunina, ásamt skriptum til að keyra þýðingar frá skipanalínu. Nánari leiðbeiningar eru í README skjalinu.

  • Semi-supervised Icelandic-Polish Translation System (22.09)

    This Icelandic-Polish translation model (bi-directional) was trained using fairseq (https://github.com/facebookresearch/fairseq) by means of semi-supervised translation by starting with the mBART50 model. The model was then trained using a multi-task curriculum to first learn to denoise sentences. Then the model was trained to translate using aligned parallel texts. Finally the model was provided with monolingual texts in both Icelandic and Polish with which it iteratively creates back-translations. For the PL-IS direction the model achieves a BLEU score of 27.60 on held out true parallel training data and 15.30 on the out-of-domain Flores devset. For the IS-PL direction the model achieves a score of 27.70 on the true data and 13.30 on the Flores devset. -- Þetta íslensk-pólska þýðingarlíkan (tvíátta) var þjálfað með fairseq (https://github.com/facebookresearch/fairseq) með hálf-sjálfvirkum aðferðum frá mBART50 líkaninu. Líkanið var þjálfað á þremur verkefnum, afruglun, samhliða þýðingum og bakþýðingum sem voru myndaðar á þjálfunartíma. Fyrir PL-IS áttina fæst BLEU skor 27.60 á raun gögnum sem voru tekin til hliðar og 15.30 á Flores þróunargögnunum. Fyrir IS-PL áttina fæst skor 27.70 á raun gögnunum og 13.30 á Flores þróunargögnunum.

  • Optimized Long Context Translation Models for English-Icelandic translations (22.09)

    ENGLISH: These models are optimized versions of the translation models released in http://hdl.handle.net/20.500.12537/278. Instead of the 24 layers used in the full model, they have been shrunk down to 7 layers. The computational resources required to run inference on the models is thus significantly less than using the original models. Performance is comparable to the original models when evaluated on general topics such as news, but for expert knowledge from the training data (e.g. EEA regulations) the original models are more capable. The models are capable of translating between English and Icelandic, in both directions. They are capable of translating several sentences at once and are robust to some input errors such as spelling errors. The models are based on the pretrained mBART25 model (http://hdl.handle.net/20.500.12537/125, https://arxiv.org/abs/2001.08210) and finetuned on bilingual EN-IS data and backtranslated data (including http://hdl.handle.net/20.500.12537/260).

Upphaflegu líkönin eru með 24 lög en þessar útgáfur eru með 7 lög og eru skilvirkari í keyrslu. Frammistaða líkananna er á pari við þau upphaflegu fyrir almennan texta, svo sem í fréttum. Á sérhæfðari texta sem er að finna í þjálfunargögnunum standa þau sig verr, t.d. á evrópureglugerðum. Þessi líkön geta þýtt á milli ensku og íslensku. Líkönin geta þýtt margar málsgreinar í einu og eru þolin gagnvart villum og smávægilegu fráviki í inntaki.
