Zaidi","Geoffrey I. Webb","Francois Petitjean","Germain Forestier"],"abstract":"We propose two general and falsifiable hypotheses about expectations on\ngeneralization error when learning in the context of concept drift. One posits\nthat as drift rate increases, the forgetting rate that minimizes generalization\nerror will also increase and vice versa. The other posits that as a learner's\nforgetting rate increases, the bias/variance profile that minimizes\ngeneralization error will have lower variance and vice versa. These hypotheses\nlead to the concept of the sweet path, a path through the 3-d space of\nalternative drift rates, forgetting rates and bias/variance profiles on which\ngeneralization error will be minimized, such that slow drift is coupled with\nlow forgetting and low bias, while rapid drift is coupled with fast forgetting\nand low variance. We present experiments that support the existence of such a\nsweet path. We also demonstrate that simple learners that select appropriate\nforgetting rates and bias/variance profiles are highly competitive with the\nstate-of-the-art in incremental learners for concept drift on real-world drift\nproblems.","url_abs":"http://arxiv.org/abs/1801.09354v2","url_pdf":"http://arxiv.org/pdf/1801.09354v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"on-the-inter-relationships-among-drift-rate","repo_url":"https://github.com/nayyarzaidi/SweetPathVoyager","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
