A development team is fine-tuning a very large, powerful language model. Instead of using human-labeled data, they use a much smaller, less capable model to generate labels for a vast dataset. The training objective is to make the large model's predictions match the small model's labels as closely as possible, viewing the process as a transfer of 'knowledge' from the small model to the large one. Based on this methodology, what is the most significant potential pitfall?

Risk of Overfitting in Weak-to-Strong Fine-Tuning
A development team is fine-tuning a very large, powerful language model. Instead of using human-labeled data, they use a much smaller, less capable model to generate labels for a vast dataset.

Analyzing the Weak-to-Strong Objective Function
Framing the process of fine-tuning a powerful model with labels from a weaker model as a form of knowledge distillation ensures that the powerful model will automatically learn to generalize beyond the weaker model's capabilities and correct its mistakes.
