| # FRED-T5-large-spell model |
|
|
| ### Summary |
| The model corrects spelling errors and typos by bringing all the words in the text to the norm of the Russian language. |
| The proofreader was trained based on the [FredT5-large](https://huggingface.co/ai-forever/FRED-T5-large) model. |
| 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 functionality of the [SAGE library](https://github.com/ai-forever/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 four available datasets: |
| - **RUSpellRU**: texts collected from ([LiveJournal](https://www.livejournal.com/media)), 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](https://github.com); |

| ## How to use |
| ```python |
| from transformers import T5ForConditionalGeneration, AutoTokenizer |
| |
| path_to_model = "ai-forever/FRED-T5-large-spell" |
| |
| model = T5ForConditionalGeneration.from_pretrained(path_to_model) |
| tokenizer = AutoTokenizer.from_pretrained(path_to_model, eos_token="</s>") |
| prefix = "Исправь: " |
| |
| sentence = "прийдя в МГТУ я был удивлен никого необноружив там…" |
| sentence = prefix + sentence |
| |
| encodings = tokenizer(sentence, return_tensors="pt") |
| generated_tokens = model.generate( |
| **encodings, eos_token_id=tokenizer.eos_token_id, early_stopping=True) |
| answer = tokenizer.batch_decode(generated_tokens, skip_special_tokens=True) |
| print(answer) |
| |
| # ["прийдя в МГТУ я был удивлен никого не обнаружив там.. «при"] |
| ``` |
