Setting Up Your Training Environment

Before embarking on this culinary journey, ensure you have the right kitchen (environment) set up:

• Frameworks Required:
  • Transformers 4.9.1
  • Pytorch 1.9.0+cu102
  • Datasets 1.11.0
  • Tokenizers 0.10.2

Training Procedure

Now, let’s break down the steps needed to train the model. Think of it like a recipe with various steps to ensure everything comes together flawlessly.

Training Hyperparameters

• Learning Rate: 3e-05
• Train Batch Size: 16
• Eval Batch Size: 8
• Seed: 42
• Optimizer: Adam (with betas=(0.9, 0.999) and epsilon=1e-08)
• Learning Rate Scheduler Type: Linear
• Warmup Ratio: 0.1
• Number of Epochs: 10

Tracking Training Results

During the training, keep an eye on your metrics as they provide feedback on how well your “dish” is cooking. Here’s an example of how you might track them:

 Training Loss  Epoch  Step   Validation Loss  Precision  Recall  F1      Accuracy:  0.6219         1.0    8235   0.3347           0.6066     0.6581  0.6313  0.9015  0.3071         2.0    16470  0.3165           0.6349     0.6637  0.6490  0.9060  0.2384         3.0    24705  0.3311           0.6373     0.6769  0.6565  0.9068  0.1834         4.0    32940  0.3414           0.6349     0.6780  0.6557  0.9069  0.1392         5.0    41175  0.3793           0.6334     0.6775  0.6547  0.9068 

Troubleshooting Common Issues

Like any recipe, things may sometimes go awry. Here are some troubleshooting ideas to keep your cooking smooth:

• High Loss Values: If your validation loss isn’t decreasing, try adjusting your learning rate or increasing the number of epochs.
• Low Precision or Recall: This could indicate class imbalance. Consider using techniques like oversampling or weighting to help.
• Training Not Converging: Ensure that your optimizer settings and hyperparameters are appropriate for your dataset.
