Difference from Steering Prototypes (Steering Prototypes with Prompt-tuning for Rehearsal-free Continual Learning)

[libo-huang]

Thanks to the authors for their interesting work.

I have noticed that there are some similarities in the implementations of HiDe-Prompt (with features such as (a) an Adapter and (b) multiple centroids obtained from KNN) and Steering Prototypes (featuring (a) a multi-layer perceptron (MLP) and (b) multi-centroid prototypes).

I am wondering about the differences between HiDe-Prompt and Steering Prototypes, although I have observed that footnote 4 indicates that Steering Prototypes is a contemporaneous work (as Steering Prototypes was publicly released on March 6, 2023, and HiDe-Prompt was on October 11, 2023 on arXiv).

Thanks in advance.
