Periodically, after taking some number $\\tau$ of base algorithm steps, workers average their parameters using ALLREDUCE and perform a momentum update.","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/1910.00643v2","title":"SlowMo: Improving Communication-Efficient Distributed SGD with Slow Momentum","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":"Distributed Methods","url":"/methods/category/distributed-methods","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":null,"papers_newest_first":[{"paper":"/paper/slowmo-improving-communication-efficient","title":"SlowMo: Improving Communication-Efficient Distributed SGD with Slow Momentum","date":"2019-10-01","arxiv_id":"1910.00643","n_code_links":2,"syntology":{"ran":0,"of":3,"unverified":3,"pointer_only":0}}],"papers_shown":1,"tasks":[{"task":"/task/blocking","name":"Blocking","papers":1},{"task":"/task/distributed-optimization","name":"Distributed Optimization","papers":1},{"task":"/task/image-classification","name":"Image Classification","papers":1},{"task":"/task/machine-translation","name":"Machine Translation","papers":1},{"task":"/task/translation","name":"Translation","papers":1},{"task":"/task/image-classification","name":"image-classification","papers":1}],"tasks_shown":6,"n_tasks":6,"usage_by_year":[{"year":"2019","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/slowmo"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
