Regarding potential missing references

[Ke Young]

Hi, you have done an excellent job, and it would be perfect if you could include highly relevant references.
The following two papers demonstrate the effectiveness of pre-training visual prompts in the few-shot scenario and are closely related.
[1] VPPT: Visual Pre-Trained Prompt Tuning Framework for Few-Shot Image Classification
[2] PVP: Pre-trained Visual Parameter-Efficient Tuning

Hi @bityangke, thanks for your reminder, and we will add the reference works in the main text. 😊
