Data Poisoning Won't Save You From Facial Recognition

1 code implementation28 Jun 2021 Evani Radiya-Dixit, Sanghyun Hong, Nicholas Carlini, Florian Tramèr

We demonstrate that this strategy provides a false sense of security, as it ignores an inherent asymmetry between the parties: users' pictures are perturbed once and for all before being published (at which point they are scraped) and must thereafter fool all future models -- including models trained adaptively against the users' past attacks, or models that use technologies discovered after the attack.

How fine can fine-tuning be? Learning efficient language models

no code implementations24 Apr 2020 Evani Radiya-Dixit, Xin Wang

Given a language model pre-trained on massive unlabeled text corpora, only very light supervised fine-tuning is needed to learn a task: the number of fine-tuning steps is typically five orders of magnitude lower than the total parameter count.
