Understanding The Model Through Analogy

Imagine training a robust pool of lifeguards – each one represents a parameter in our DistilBERT model. Just as the lifeguards first undergo rigorous training sessions to hone their skills (analogous to the training epochs), they gradually grow more adept at spotting dangers in the water (akin to loss reduction during training).

Each training epoch corresponds to a different session where the lifeguards improve their observation techniques (parameter adjustments), leading to better safety measures (increased accuracy). The end result? A skilled team ready to handle diverse aquatic situations—just like our model, trained to classify various types of text accurately!

Troubleshooting Common Issues

• Low Accuracy: If you observe accuracy lower than expected, check the training parameters—especially the learning rate and batch size. Additionally, be sure the dataset is clean and representative of the tasks at hand.
• Training Crashes: Insufficient GPU memory often leads to training crashes. Consider reducing the train_batch_size or using gradient accumulation to alleviate the burden on resources.
• Overfitting: If your model performs well on training data but poorly on validation data, this may indicate overfitting. You can introduce dropout layers or augment your dataset to enhance generalization.
