Question :Black Box substitute model implementation

[3ntr0phy]

Hello!
I was wondering if the framework has an implementation of the black box surrogate model :) I found it in the old version of it but not the recent.
Thanks

Could you elaborate a bit on your use case? is bpda something that you are looking for https://github.com/BorealisAI/advertorch/blob/master/advertorch/bpda.py ?

I was thinking about an implementation of this type of attack https://arxiv.org/abs/1602.02697.
Thank you for the reply !

Hello there, we are indeed planning to extend advertorch's capabilities to work in the black box setting. Stay tuned!

Presently, we are focused on approaches that use gradient approximations and gradient-free optimization. In the literature, these tend to be more query efficient, and have better success rates. Is there a specific use-case you are working on that requires a surrogate model?
