In the ever-evolving field of artificial intelligence, training a token classification model can feel like navigating through a dense forest without a map. However, with the right knowledge and step-by-step guidance, you can pave a clear path to success. This blog outlines how to train a fine-tuned version of a model like bert-base-uncased on the coNLL-2003 dataset.
What is Token Classification?
Token classification refers to the process of assigning labels to tokens in a sentence, enabling applications like Named Entity Recognition (NER). Think of it as having a librarian categorize books by genre; every token is scrutinized and placed into its correct category.
Model Overview
This particular model, aptly named this_is_my_model, has been fine-tuned on the coNLL-2003 dataset and boasts impressive metrics:
- Precision: 0.8674
- Recall: 0.9021
- F1 Score: 0.8844
- Accuracy: 0.9762
Gathering Your Tools
In order to train this model, the following tools and libraries are essential:
- Transformers 4.25.1
- Pytorch 1.13.0+cu116
- Datasets 2.7.1
- Tokenizers 0.13.2
Training Procedure
The training procedure is like baking a cake; you need precise ingredients and steps. Here’s a breakdown:
- Learning Rate: 2e-05
- Train Batch Size: 16
- Eval Batch Size: 16
- Seed: 42
- Optimizer: Adam with betas=(0.9, 0.999) and epsilon=1e-08
- Learning Rate Scheduler: Linear

Interpreting Training Results
The following table summarizes key training results:
| Training Loss | Epoch | Step | Validation Loss | Precision | Recall | F1 | Accuracy |
|---------------|-------|-------|-----------------|-----------|--------|-------|----------|
| 0.2292 | 1.0 | 878 | 0.1048 | 0.8683 | 0.8973 | 0.8825| 0.9763 |
| 0.0493 | 2.0 | 1756 | 0.1143 | 0.8674 | 0.9021 | 0.8844| 0.9762 |
This table helps us see how the model improves over time, much like tracking the growth of a plant through various seasons.
Troubleshooting Your Model Training
Even the best-laid plans can run into obstacles. Here are some common issues you might encounter during model training:
- High Validation Loss: Indicates your model may not be enjoying the training. Adjust your learning rate or increase the number of epochs.
- Poor Precision or Recall: Your model might be struggling with underfitting or overfitting. Consider revisiting your dataset or fine-tuning your parameters.
- Hardware Limitations: Ensure your GPU is adequately powerful and not bottlenecking the training process.
