{"url":"/method/limix","slug":"limix","name":"LIMix","full_name":"Lifelong Infinite Mixture","full_name_withheld":false,"description_markdown":"**LIMix**, or **Lifelong Infinite Mixture**, is a lifelong learning model which grows a mixture of models to adapt to an increasing number of tasks.  LIMix can automatically expand its network architectures or choose an appropriate component to adapt its parameters for learning a new task, while preserving its previously learnt information. Knowledge is incorporated by means of Dirichlet processes by using a gating mechanism which computes the dependence between the knowledge learnt previously and stored in each component, and a new set of data. Besides, a Student model is trained which can accumulate cross-domain representations over time and make quick inferences.","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/2108.12278v1","title":"Lifelong Infinite Mixture Model Based on Knowledge-Driven Dirichlet Process","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":"Lifelong Learning","url":"/methods/category/lifelong-learning","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":null,"papers_newest_first":[{"paper":"/paper/lifelong-infinite-mixture-model-based-on","title":"Lifelong Infinite Mixture Model Based on Knowledge-Driven Dirichlet Process","date":"2021-08-25","arxiv_id":"2108.12278","n_code_links":1,"syntology":null}],"papers_shown":1,"tasks":[{"task":"/task/lifelong-learning","name":"Lifelong learning","papers":1}],"tasks_shown":1,"n_tasks":1,"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/limix"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
