Fine-tuning a language model can feel overwhelming, but with the right guidance, it becomes an exciting journey into the realm of Natural Language Processing (NLP). In this article, we will explore the process of fine-tuning the distilbert-base-multilingual-cased model for sentiment analysis specifically for Albanian language data.

Understanding the Basics

Imagine the DistilBERT model as a sponge—it has absorbed a lot of knowledge about multiple languages from various text sources. However, to specialize in a particular skill, like understanding sentiments in Albanian, it needs to be squeezed (fine-tuned) with specific training data. This training data is like a recipe that teaches the sponge how to identify whether a text is positive, negative, or neutral based on recipes (datasets) from past experiences.

Model Details

This model, called distilbert-base-multilingual-cased-finetuned-sentiment-albanian, is a fine-tuned version of the aforementioned base model. The training results show promising abilities to identify sentiments with:

• Loss: 0.3126
• F1-score: 0.9393
• Accuracy score: 0.8902

Training Procedure

Now, let’s take a look at how to actually fine-tune your model:

Training Hyperparameters

During the training process, several hyperparameters are crucial:

• learning_rate: 2e-05
• train_batch_size: 64
• eval_batch_size: 64
• seed: 42
• optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
• lr_scheduler_type: linear
• num_epochs: 3

Training Results Summary

The model was evaluated over 3 epochs, showing an improvement in the training and validation loss:

Epoch |  Validation Loss |  F1-score |  Accuracy score
-------------------------------------------------------
1.0   |  0.3424         |  0.9290  |  0.8675
2.0   |  0.3174         |  0.9362  |  0.8822
3.0   |  0.3126         |  0.9393  |  0.8902

Troubleshooting Common Issues

While fine-tuning, you may encounter some common issues. Here are troubleshooting ideas to help you out:

• High Loss Value: This could indicate that your model is not learning effectively. Ensure that your learning rate is not too high and consider tweaking your dataset.
• Overfitting: If the training accuracy is increasing while the validation accuracy stagnates, you may need to introduce more regularization techniques or gather more diverse training data.
• Performance on New Data: If the model struggles with unseen data, revisit your training dataset and ensure it is representative of the various sentiments you want the model to understand.
