This was an unfortunate mistake, sorry about that. But the conclusions of our paper don't change drastically: there is significant gradient masking (as shown by the transfer attack) and the cifar robustness is at most in the 15% range. Still cool though! We'll see if we can fix the full attack

🚨Unlearned hazardous knowledge can be retrieved from LLMs 🚨 Our results show that current unlearning methods for AI safety only obfuscate dangerous knowledge, just like standard safety training. Here's what we found👇

Ensemble Everything Everywhere is a defense against adversarial examples that people got quite exited about a few months ago (in particular, the defense causes "perceptually aligned" gradients just like adversarial training) Unfortunately, we show it's not robust... arxiv.org/abs/2411.14834

Gradient Masking All-at-Once: Ensemble Everything Everywhere Is Not Robust

Ensemble everything everywhere is a defense to adversarial examples that was recently proposed to make image classifiers robust. This defense works by ensembling a model's intermediate representations...
