In contrast to previous attacks that attempt to recover pre-fine-tuning capabilities, Spectral DeTuning aims to recover the exact pre-fine-tuning *weights*. Spectral DeTuning can exploit this vulnerability against large-scale models such as a personalized Stable Diffusion and an aligned Mistral.","description_state":"present","introduced_year":null,"introduced_by":{"title":"Recovering the Pre-Fine-Tuning Weights of Generative Models","paper":"/paper/recovering-the-pre-fine-tuning-weights-of","first_author":"Eliahu Horwitz","n_authors":3,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/recovering-the-pre-fine-tuning-weights-of"},"source":{"url":"https://arxiv.org/abs/2402.10208v2","title":"Recovering the Pre-Fine-Tuning Weights of Generative Models","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"General","area_id":"general","collection":"Fine-Tuning","url":"/methods/category/fine-tuning","pwc_aliases":[]},{"area":"General","area_id":"general","collection":"Inference Attack","url":"/methods/category/inference-attack","pwc_aliases":[]},{"area":"","area_id":"","collection":"Pre-Fine-Tuning Weight Recovery","url":"/methods/category/pre-fine-tuning-weight-recovery","pwc_aliases":[]},{"area":"General","area_id":"general","collection":"Adversarial Attacks","url":"/methods/category/adversarial-attacks","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/recovering-the-pre-fine-tuning-weights-of","title":"Recovering the Pre-Fine-Tuning Weights of Generative Models","date":"2024-02-15","arxiv_id":"2402.10208","n_code_links":1,"syntology":{"ran":2,"of":4,"unverified":2,"pointer_only":4}}],"papers_shown":1,"tasks":[{"task":"/task/pre-fine-tuning-weight-recovery","name":"Pre-Fine-Tuning Weight Recovery","papers":1}],"tasks_shown":1,"n_tasks":1,"usage_by_year":[{"year":"2024","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/spectral-detuning"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
