{"url":"/method/morphence","slug":"morphence","name":"Morphence","full_name":"Morphence","full_name_withheld":false,"description_markdown":"**Morphence** is an approach for adversarial defense that shifts the defense landscape by making a model a moving target against adversarial examples. By regularly moving the decision function of a model, Morphence makes it significantly challenging for repeated or correlated attacks to succeed. Morphence deploys a pool of models generated from a base model in a manner that introduces sufficient randomness when it responds to prediction queries. To ensure repeated or correlated attacks fail, the deployed pool of models automatically expires after a query budget is reached and the model pool is replaced by a new model pool generated in advance.","description_state":"present","introduced_year":null,"introduced_by":{"title":null,"paper":null,"first_author":null,"n_authors":0,"url_abs":null,"archive_paper_url":null},"source":{"url":"https://arxiv.org/abs/2108.13952v4","title":"Morphence: Moving Target Defense Against Adversarial Examples","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":"Adversarial Attacks","url":"/methods/category/adversarial-attacks","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":null,"papers_newest_first":[{"paper":"/paper/morphence-moving-target-defense-against","title":"Morphence: Moving Target Defense Against Adversarial Examples","date":"2021-08-31","arxiv_id":"2108.13952","n_code_links":1,"syntology":null}],"papers_shown":1,"tasks":[{"task":"/task/image-classification","name":"Image Classification","papers":1},{"task":"/task/image-classification","name":"image-classification","papers":1}],"tasks_shown":2,"n_tasks":2,"usage_by_year":[{"year":"2021","papers":1}],"row_source":"embedded","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/morphence"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
