Fine-tuning a machine learning model can feel like preparing a gourmet dish; you need the right ingredients and a solid recipe. In this guide, we will explore how to fine-tune the DSPFirst-Finetuning-1 model, based on a Q&A dataset derived from the DSPFirst textbook.

Understanding the Dataset

This model is built upon the ahotrodelectra_large_discriminator_squad2_512 base and focused on the SQuAD 2.0 format. It uses an 80% training and 20% test split with a total of:

• Training Rows: 4755
• Test Rows: 1189

An excellent visualization of the dataset can be seen here.

Training Procedure

Just like a chef carefully selects their cooking technique, setting appropriate hyperparameters is essential when training your model. Below are the exact hyperparameters used for the fine-tuning:

• 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
• Learning rate scheduler type: Linear
• Number of epochs: 4

Model Descriptions and Limitations

While fine-tuning, remember that since the datasource is generated from the DSPFirst textbook, the quality of the dataset is not guaranteed. It’s important to evaluate and possibly refine your dataset to ensure optimal results.

Training Results

Monitor the training loss alongside validation loss. Here’s a peek at the training results.

 Training Loss  Epoch  Step   Validation Loss
6.0131         0.7    20    0.9549
6.1542         1.42   40    0.9302
6.1472         2.14   60    0.9249
5.9662         2.84   80    0.9248
6.1467         3.56   100   0.9236

Framework Versions

Utilize the following frameworks to ensure compatibility:

• Transformers: 4.18.0
• Pytorch: 1.10.0+cu111
• Datasets: 2.1.0
• Tokenizers: 0.12.1

Troubleshooting

If you encounter issues during the training process, here are some strategies to resolve them:

• Check your dataset for inconsistencies.
• Adjust your hyperparameters if the model isn’t converging.
• Ensure compatibility of framework versions.
• Review loss values for signs of overfitting or underfitting.
