P-Distill: Efficient and Effective Prompt Tuning Using Knowledge Distillation

Blog Article

In the field of natural language processing (NLP), prompt-based learning is widely used for efficient parameter learning.However, this method has the drawback airpods in jacksonville of shortening the input length by the extent of the attached prompt, leading to the inefficient utilization of the input space.In this study, we propose P-Distill, a novel prompt compression method that mitigates the aforementioned limitation of prompt-based learning while maintaining performance via knowledge distillation.

The knowledge distillation process of P-Distill consists of two methods, namely prompt initialization and prompt distillation.Experiments on various NLP tasks demonstrated that P-Distill exhibited comparable or superior performance compared to other state-of-the-art prompt-based learning methods, even with significantly shorter prompts.Specifically, we achieved a peak improvement of 1.

90% even with the prompt lengths compressed to one-eighth.An additional study further provides here insights into the distinct impact of each method on the overall performance of P-Distill.Our code will be released upon acceptance.
