In the world of Natural Language Processing (NLP), creating a model that understands and classifies text accurately can be a challenging yet fulfilling endeavor. Today, we will discuss how to fine-tune the phobert-large model specifically for the Vietnamese students feedback dataset. This model boasts impressive accuracy metrics, making it an excellent choice for text classification tasks.

Understanding the phobert-large Model

The phobert-large model has been particularly fine-tuned to process Vietnamese text effectively. Based on the vinaiphobert-large architecture, it provides a framework that incorporates BERT-like capabilities tailored for the Vietnamese language. This means it can understand context, perform sentiment analysis, and categorize text with higher accuracy.

Key Metrics Achieved

• Loss: 0.2285
• Accuracy: 94.63%

Such high accuracy indicates that the model effectively understands the nuances of student feedback, leading to reliable classifications.

Training Procedure Breakdown

Fine-tuning this model involves a well-structured training methodology. Let’s explore the training hyperparameters that were utilized:

• Learning Rate: 2e-05
• Training Batch Size: 24
• Evaluation Batch Size: 24
• Seed: 42
• Optimizer: Adam
• Learning Rate Scheduler Type: Linear
• Number of Epochs: 3
• Mixed Precision Training: Native AMP

These parameters are pivotal as they directly influence how effectively the model learns from the dataset during the training phase.

Training Results Examination

Here is how the training progressed over the epochs:

Training Loss, Epoch, Step, Validation Loss, Accuracy:
No log   1.0  477   0.2088  0.9375
0.3231   2.0  954   0.2463  0.9444
0.1805   3.0  1431  0.2285  0.9463

Think of the training process as teaching a student—at first, they might struggle with concepts (high loss), but over time, with practice, they gradually understand and improve (lower loss and higher accuracy). This analogy highlights how the model learns from mistakes and improves progressively through epochs.

Troubleshooting Common Issues

If you encounter challenges while training or evaluating the model, consider the following troubleshooting ideas:

• Ensure that your dataset is properly formatted. Misalignments can lead to unexpected behavior during training.
• If you experience performance issues, check your batch sizes; sometimes reducing them can help manage memory better.
• Adjust hyperparameters like the learning rate for optimization; sometimes a lower learning rate can yield better learning outcomes.
• Monitor logs and metrics closely during training to address issues as they arise.
