How to Use RuPERTa-Base for Paraphrase Identification

May 22, 2021

Welcome to our guide on leveraging the power of RuPERTa-Base, specially fine-tuned on the PAWS-X dataset for paraphrase identification in Spanish!

What is RuPERTa-Base?

RuPERTa-Base is a state-of-the-art language model designed to understand and process natural language. By utilizing the PAWS-X dataset, it has been finely tuned for tasks such as paraphrase identification (NLI). This means it can discern whether two sentences express the same idea in different ways.

Getting Started with RuPERTa-Base

Step 1: Ensure you have the necessary libraries installed. You will primarily need Hugging Face’s Transformers library.
Step 2: Load the RuPERTa-Base model using the pre-trained weights.
Step 3: Input your sentences and run them through the model to identify whether they are paraphrasing each other.

Example Code

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("datafinland/ruPERTa-base-paws-x-es")
model = AutoModelForSequenceClassification.from_pretrained("datafinland/ruPERTa-base-paws-x-es")

# Prepare inputs
sentence1 = "En 2009 se mudó a Filadelfia."
sentence2 = "Ahora vive en Nueva York."
inputs = tokenizer(sentence1, sentence2, return_tensors='pt', padding=True)

# Get predictions
with torch.no_grad():
    logits = model(**inputs).logits
    predicted_class_id = logits.argmax().item()

# Output result
print(f"Paraphrase Identified: {predicted_class_id}")

In the code above, imagine that you are a chef in a kitchen trying to prepare the same dish using different ingredients. Each step goes as follows:

You load your ingredients (tokenizer and model).
You prepare your two versions of the dish (your sentences).
You set the cooking (perform the model’s prediction), and finally, you check if they taste the same (output the prediction).

Troubleshooting

If you run into issues while working with RuPERTa-Base, consider the following troubleshooting steps:

Verify library versions: Ensure that the Transformers library is up-to-date.
Input formatting: Ensure your sentences are pre-processed correctly. They should be compatible with the model’s expectations.
GPU vs CPU: Check if you’re running on a GPU. If performance is slow, using a compatible GPU will help speed up processing.
CUDA errors: If you encounter CUDA out of memory errors, try reducing batch sizes or clearing the GPU memory.
