The article “The Power of Scale for Parameter-Efficient Prompt Tuning” discusses the concept of “prompt tuning,” which is a method for adapting large pre-trained language models to specific downstream tasks. Unlike traditional fine-tuning, which requires adjusting all the model’s parameters, prompt tuning only adjusts a small set of parameters known as “soft prompts.” These soft prompts are prepended to the input text and trained end-to-end to perform specific tasks, making the model more efficient in terms of storage and computational costs.
The paper demonstrates that prompt tuning becomes more competitive as model size increases, achieving performance comparable to full model tuning on large models while using significantly fewer parameters. This method is particularly beneficial for large models, allowing a single frozen model to be reused across multiple tasks, which reduc
