How to obtain the adv_init?

Hi, @max-andr

Thanks for your great work.

Could you please share the script for searching the adv_init?

Like the one for llama-2

adv_init = "repeated Dezprüngtemplates AlfмичеnonINSTár Luci expr '\ These<!-- телеireế진 fue [`мости{ originallyinger [{ritWordльноpersistenceбран Viewshipică neboीHold Item}}$ءwikipediaватиո"

Hi Xiaosen,

Thanks for interest in our work!

This is what we describe in the paper as self-transfer:

We leverage the adversarial suffix found by random search for a simpler harmful request as the initialization for RS on more challenging requests. We refer to this approach as self-transfer.

There is no script for this procedure: you just go to the log files of a run with the default initialization (such as https://github.com/tml-epfl/llm-adaptive-attacks/blob/main/attack_logs/exps_llama2-7b_plain_init.log), extract an adversarial suffix (ideally, optimized for as many iterations as possible) that is successful on some example, and then insert it in main.py as adv_init.

Interestingly, this approach often leads to a transferable adversarial suffix (or, at least, a good starting for a subsequent run of random search), even though it's crafted for a single model and a single request.

I hope that helps.

Best, Maksym
