🚀 sage-mt5-large
The sage-mt5-large model corrects spelling errors and typos in both Russian and English, bringing text to language norms. It's based on the mT5-large architecture and trained with an extensive dataset with artificial errors.
🚀 Quick Start
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tokenizer = AutoTokenizer.from_pretrained("ai-forever/sage-mt5-large")
model = AutoModelForSeq2SeqLM.from_pretrained("ai-forever/sage-mt5-large", device_map='cuda')
sentence = "Перведи мне текст на аглиском: \"Screw you kuys, I am goin hme (c)."
inputs = tokenizer(sentence, max_length=None, padding="longest", truncation=False, return_tensors="pt")
outputs = model.generate(**inputs.to(model.device), max_length = inputs["input_ids"].size(1) * 1.5)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
✨ Features
- Corrects spelling errors and typos in both Russian and English.
- Based on the mT5-large architecture.
- Trained with an extensive dataset with “artificial” errors created using the SAGE library.

Summary
The model corrects spelling errors and typos in both Russian and English languages by bringing all the words in the text to the norm of the language. The corrector was trained based on the model mT5-large architecture. An extensive dataset with “artificial” errors was taken as a training corpus: the corpus was assembled on the basis of the Russian-language Wikipedia and transcripts of Russian-language videos, then typos and spelling errors were automatically introduced into it using the library SAGE.

Metrics
Quality
Below are automatic metrics for determining the correctness of the spell checkers. We compare our solution with both open automatic spell checkers and the ChatGPT family of models on all six available datasets:
- RUSpellRU: texts collected from (LiveJournal), with manually corrected typos and errors.
- MultidomainGold: examples from 7 text sources, including the open web, news, social media, reviews, subtitles, policy documents and literary works.
- MedSpellChecker: texts with errors from medical anamnesis.
- GitHubTypoCorpusRu: spelling errors and typos in commits from GitHub.
- BEA60K: English spelling errors collected from several domains.
- JFLEG: 1601 sentences in English, which contain about 2 thousand spelling errors.
RUSpellRU, MultidomainGold, MedSpellChecker, GitHubTypoCorpusRu are datasets for the Russian spellchecking and BEA60K and JFLEG are those for the English language.
