Our clustering-based strategy is composed of two steps. In the first step, we divide the potential nodes into several groups via clustering analysis and apply Bayesian network structure learning to obtain some pre-existing arcs within each cluster. In the second step, with all the within-cluster arcs being well preserved, we learn the between-cluster structure of the given network. Experimental results on benchmark datasets show that a wide range of structure learning algorithms benefit from the proposed clustering-based strategy in terms of both accuracy and efficiency.\n \n <\/jats:p>","DOI":"10.1609\/aaai.v32i1.12129","type":"journal-article","created":{"date-parts":[[2022,6,21]],"date-time":"2022-06-21T20:14:33Z","timestamp":1655842473000},"source":"Crossref","is-referenced-by-count":2,"title":["Bayesian Network Structure Learning: The Two-Step Clustering-Based Algorithm"],"prefix":"10.1609","volume":"32","author":[{"given":"Yikun","family":"Zhang","sequence":"first","affiliation":[]},{"given":"Jiming","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2018,4,29]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/12129\/11988","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/12129\/11988","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T18:50:37Z","timestamp":1667847037000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/12129"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,4,29]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,2,8]]}},"URL":"http:\/\/dx.doi.org\/10.1609\/aaai.v32i1.12129","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2018,4,29]]}}}
