Model description

Trained with this jupiter notebook

Intended uses & limitations

In order to reduce the number of characters, the following letters have been replaced or removed:

• 'я' -> 'йа'
• 'ю' -> 'йу'
• 'ё' -> 'йо'
• 'е' -> 'йэ' for first letter
• 'е' -> 'э' for other cases
• 'ъ' -> deleted
• 'ь' -> deleted

Therefore, in order to get the correct text, you need to do the reverse transformation and use the language model.
