If you’re interested in paraphrasing texts in Russian, you’ve come to the right place! Here, we’ll explain how to utilize a small Russian paraphraser developed from the google/mt5-small model. While its performance may not be stellar out of the box, it can be fine-tuned for better results!

Understanding the Model

This model was created by simplifying an existing model, alenusch/mt5small-ruparaphraser. It underwent a significant reduction in its vocabulary size, stripping away 96% of non-Russian or infrequent vocabulary. Here’s a quick analogy to help you visualize this:

• Imagine a chef (the model) who normally has a giant pantry filled with various ingredients (vocabulary).
• This chef decides to cook only Russian dishes, so he gets rid of all the unnecessary ingredients, leaving him with just the essential ones needed for his cuisine.
• As a result, he becomes more efficient (better performance with less overhead), but the variety of dishes he can make (paraphrasing styles) might be limited without further customization.

Model Parameters and Size

Originally, the model had 300 million parameters, but through vocabulary reduction, it now operates with just 65 million parameters, significantly decreasing its size from 1.1GB to a manageable 246MB. This means that while it’s lightweight, it can still be capable of generating varied sentences.

Installation and Basic Usage

To get started with this paraphraser, follow these steps:

1. Install necessary packages:

# !pip install transformers sentencepiece

2. Import the libraries:

import torch
from transformers import T5ForConditionalGeneration, T5Tokenizer

3. Initialize the tokenizer and model:

tokenizer = T5Tokenizer.from_pretrained("cointegrated/rut5-small")
model = T5ForConditionalGeneration.from_pretrained("cointegrated/rut5-small")

4. Provide the text you want to paraphrase:

text = 'Ехал Грека через реку, видит Грека в реке рак.'

5. Tokenize the input and generate hypotheses:

inputs = tokenizer(text, return_tensors='pt')
with torch.no_grad():
    hypotheses = model.generate(
        **inputs,
        do_sample=True,
        top_p=0.95,
        num_return_sequences=10,
        repetition_penalty=2.5,
        max_length=32,
    )
for h in hypotheses:
    print(tokenizer.decode(h, skip_special_tokens=True))

Troubleshooting

If you encounter issues while using the model, consider the following troubleshooting tips:

• Ensure that you have installed the required libraries correctly.
• Check if your input text is properly formatted and not exceeding the max length specified.
• Adjust sampling parameters like top_p and repetition_penalty for different paraphrasing styles.
