Training Procedure

The training process involves a series of hyperparameters that dictate how the model learns. Imagine this process as nurturing a plant—the right amount of water, sunlight, and soil quality can lead to a flourishing result. Here’s a breakdown of the hyperparameters used during training:

- learning_rate: 2e-05
- train_batch_size: 6
- eval_batch_size: 6
- seed: 42
- gradient_accumulation_steps: 86
- total_train_batch_size: 516
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
- lr_scheduler_type: linear
- num_epochs: 3

Model Hyperparameters

The model also comes with defined hyperparameters to manage its architecture:

• hidden_dropout_prob: 0.3
• attention_probs_dropout_prob: 0.3

Training Results

The training journey was carefully monitored to ensure everything was going according to plan. The following summarizes the training loss, validation loss, Exact Match, and F1 results through each epoch:

Training Loss  Epoch  Step  Validation Loss  Exact    F1
:-------------::-----::----::---------------::-------::-------
0.8393         0.98   28    0.8157           66.1060  73.0203
0.7504         1.98   56    0.7918           66.3583  72.4657
0.691          2.98   84    0.8057           65.9378  72.3603

Troubleshooting

As with any endeavor, you may encounter hiccups along the way. Here are some common issues and their solutions:

• Model Not Converging: If your model isn’t performing well, consider adjusting your learning rate or batch size.
• Overfitting: If you see training scores becoming significantly better than validation scores, try implementing techniques like dropout or increasing your training data.
• Data Issues: Always check your dataset’s integrity. Make sure there are no missing values or mismatches in your data.
