A Wolf in Sheep's Clothing: Generalized Nested Jailbreak Prompts can Fool Large Language Models Easily

1 code implementation14 Nov 2023 Peng Ding, Jun Kuang, Dan Ma, Xuezhi Cao, Yunsen Xian, Jiajun Chen, ShuJian Huang

Finally, we analyze the failure of LLMs defense from the perspective of prompt execution priority, and propose corresponding defense strategies.

A Fast MR Fingerprinting Simulator for Direct Error Estimation and Sequence Optimization

no code implementations25 May 2021 Siyuan Hu, Stephen Jordan, Rasim Boyacioglu, Ignacio Rozada, Matthias Troyer, Mark Griswold, Debra McGivney, Dan Ma

During optimization, the spatial response function is independent of sequence design and does not need to be recalculated.
