How to Fine-Tune a Model for Named Entity Recognition (NER) Using the Small-E-Czech-WikiAnn Dataset

Mar 13, 2022 | Educational

Fine-tuning models for Named Entity Recognition can sound like a daunting task, but it doesn’t have to be! In this article, we’ll walk through the steps of fine-tuning the small-e-czech model on the WikiAnn dataset, as well as evaluate its performance metrics. Let’s get started!

Understanding Token Classification

In the realm of Natural Language Processing (NLP), token classification is akin to teaching a child to recognize different types of fruits. For example, when you see a round, red fruit, you teach them it’s an “apple.” Similarly, in token classification, we teach the model to recognize different entities (like names, locations, etc.) within text.

Getting Started with the Small-E-Czech Model

This specific model, small-e-czech-finetuned-ner-wikiann, has been fine-tuned on the WikiAnn dataset, which is tailored for various languages and incorporates annotations for named entities. Once fine-tuned, the model achieved the following metrics:

  • Precision: 0.8713
  • Recall: 0.8970
  • F1 Score: 0.8840
  • Accuracy: 0.9557

Training the Model

Training a model involves setting specific hyperparameters that dictate how the learning process will occur. For our fine-tuning, we set the following properties:

  • Learning Rate: 2e-05
  • Training Batch Size: 8
  • Evaluation Batch Size: 8
  • Seed: 42
  • Optimizer: Adam with betas=(0.9, 0.999) and epsilon=1e-08
  • Learning Rate Scheduler: Linear
  • Number of Epochs: 20

Training Results

The training log provides valuable insights into how the model improved over 20 epochs. Below are some key observations:

Training Loss   Epoch   Step    Validation Loss   Precision   Recall   F1       Accuracy
0.2924          1.0     2500   0.2449           0.7686      0.8088  0.7882   0.9320
...
0.2547          20.0    50000  0.2547           0.8713      0.8970  0.8840   0.9557

Here, we can see that with each epoch, the precision, recall, F1, and accuracy generally improved, showcasing the model’s learning capability!

Troubleshooting Tips

Even the best-laid plans can go awry. If you run into issues during your fine-tuning process, consider these troubleshooting tips:

  • Verify that your dataset is properly formatted and compatible with the model.
  • Inspect hyperparameters; sometimes a slight adjustment in the learning rate can lead to better performance.
  • Ensure that the computational resources (like GPU settings) are correctly configured to avoid slow training times.
  • Check the model compatibility with installed packages, e.g., Transformers, PyTorch, etc.
