Sentence Embedding Leaks More Information than You Expect: Generative Embedding Inversion Attack to Recover the Whole Sentence (2023.findings-acl)
Copied to clipboard
| Challenge: | Sentence-level representations are beneficial for various natural language processing tasks. |
| Approach: | They propose a generative embedding inversion attack that reconstructs input sequences based only on their sentence embeddeds. |
| Outcome: | The proposed model outperforms previous embedding inversion attacks in classification metrics and generates coherent and contextually similar sentences as original inputs. |
Multi-step Jailbreaking Privacy Attacks on ChatGPT (2023.findings-emnlp)
Copied to clipboard
| Challenge: | With the rapid evolution of large language models (LLMs), many downstream NLP tasks can be well solved given appropriate prompts. |
| Approach: | They propose to integrate ChatGPT and Bing GPT3 into their applications to create a set of LLMs that can be used to generate NLP tasks with appropriate prompts. |
| Outcome: | The proposed models can be zero-shot or few-shot learners to solve specified tasks and can even be zero or few shot learners. |
