In the realm of Natural Language Processing (NLP), models like XLM-RoBERTa have become essential tools for tasks such as text classification. This blog will guide you through the process of fine-tuning the XLM-RoBERTa model on the XNLI dataset, providing insights into the training parameters and expected outcomes.
Getting Started with Your Model
First, ensure you have the necessary libraries installed. You’ll need Transformers, Pytorch, and other relevant libraries for your machine learning environment.
Understanding the Training Procedure
The training procedure includes several hyperparameters that help optimize the model’s performance. Think of these hyperparameters as seasoning in a recipe: just the right amount can make your dish perfect!
Key Hyperparameters
- Learning Rate: 2e-05
- Training Batch Size: 128
- Evaluation Batch Size: 128
- Seed: 42
- Optimizer: Adam (with betas=(0.9,0.999) and epsilon=1e-08)
- Number of Epochs: 10
Training and Evaluation Data
The model is fine-tuned on the XNLI dataset and achieves the following evaluation results:
- Validation Loss: 0.8306
- Accuracy: 0.7498
These metrics suggest the model’s capability in correctly classifying text data, with an accuracy of approximately 75%.

Troubleshooting Common Issues
While training your text classification model, you may encounter some hiccups. Here are a few common issues along with solutions:
- Issue: Model is not converging.
- Solution: Adjust the learning rate to see if a smaller value might help the model learn better.
- Issue: High validation loss.
- Solution: Check for overfitting or try increasing the training dataset size.
- Issue: Out of memory errors during training.
- Solution: Reduce the batch size or use gradient accumulation to train in smaller increments.
