In the world of natural language processing (NLP), creating and training language models has become a fascinating and rewarding endeavor. Today, we’ll dive into how to create a distilled Japanese GPT-2 model. This article is tailored to help you navigate the process smoothly, regardless of your experience level.

Understanding the Basics

The distilled model we are discussing is derived from the rinnajapanese-gpt2-medium. Think of this as a student model learning from a teacher (the original model) to generate text in Japanese.

Preparing for Distillation

• Gather Requirements: Make sure you have access to the datasets and the training code.
• Set Up the Environment: Utilize HuggingFace’s Transformers library and make necessary alterations for data handling.

Training the Model

For training, you will need to take the following steps:

• Acquire GCP credits from the Google Startup Program for resources.
• Utilize an A2-highgpu-4 instance (A100 x 4). This allows you to handle intensive computational tasks efficiently.
• Train the model for about 4 months, including some stops and resumes as necessary.

Evaluating Model Performance

Once training is complete, it’s essential to evaluate your model’s accuracy. Here, we use perplexity as a measure. The model achieves around a 40 perplexity score using the Wikipedia corpus. For reference, the teacher model, rinnajapanese-gpt2-medium, scores around 27. Although our distilled model is not as effective, it’s still functional and valuable.

Using the Tokenizer

Since the repository does not include a tokenizer specifically, you should utilize the tokenizer that comes with the rinnajapanese-gpt2-medium model. This tokenizer is essential for text processing before feeding data into the model.

Troubleshooting Tips

If you run into issues during the distillation process, here are some troubleshooting ideas:

• Ensure that you have the correct training code implemented. It can often lead to loss in accuracy if not modified properly.
• Monitor the computational resources to avoid interruptions. Insufficient resources can cause failed training sessions.
• Try varying training hyperparameters. If perplexity increases unexpectedly, adjustments may be needed.
