Fine-Tuning
In this design pattern, you’ll learn about effective strategies for fine-tuning pre-trained language models.
Fine-tuning LLMs addresses a fundamental optimization problem in transfer learning: Pre-training on large datasets helps LLMs learn general language skills and knowledge, but the differences between the pre-training data and the data for specific tasks can reduce performance. Fine-tuning uses a smaller, carefully chosen dataset for the task to update the model, making it better suited to the task’s needs. This process retains useful knowledge from pre-training while refining the model’s ability to perform effectively on the target task.
In this chapter, we’ll be covering the following topics:
- Implementing transfer learning and fine-tuning
- Strategies for freezing and unfreezing layers
- Learning rate scheduling
- Domain-specific techniques
- Few-shot and zero-shot fine-tuning
- Continual fine-tuning and catastrophic...
