When the generation speed of massive streaming data far exceeds the processing speed of a single node and the generated data need to be processed in real time, traditional centralized learning models are challenging in meeting the efficiency requirements. Therefore, online distributed learning models emerge. As time progresses, features may continuously emerge from various sources in a distributed and heterogeneous fashion. Therefore, we study the problem of online distributed heterogeneous streaming feature selection and propose a novel framework to address it, named DHSFS. The framework comprises two main components: sub-node streaming feature selection and global information synchronization. The sub-node component uses a dynamic strategy to select strong features, discard irrelevant ones, and cache weakly relevant features. In the global information synchronization stage, each sub-node synchronizes statistics information with the master node to adjust the global thresholds dynamically. Finally, the features selected by each sub-node are summarized and output. Experiments on 16 datasets show that the DHSFS framework has both high prediction accuracy and high efficiency of online stream feature selection.<\/jats:p>","DOI":"10.1145\/3767722","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T13:49:05Z","timestamp":1757944145000},"page":"1-23","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Online Distributed Heterogeneous Streaming Feature Selection"],"prefix":"10.1145","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3607-0022","authenticated-orcid":false,"given":"Peng","family":"Zhou","sequence":"first","affiliation":[{"name":"Anhui University, Hefei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4482-7873","authenticated-orcid":false,"given":"Huiqi","family":"Deng","sequence":"additional","affiliation":[{"name":"Anhui University, Hefei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3768-2610","authenticated-orcid":false,"given":"Yunyun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Anhui University, Hefei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4812-6676","authenticated-orcid":false,"given":"Zhaolong","family":"Ling","sequence":"additional","affiliation":[{"name":"Anhui University, Hefei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2396-1704","authenticated-orcid":false,"given":"Xindong","family":"Wu","sequence":"additional","affiliation":[{"name":"Hefei University of Technology, Hefei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2025,10,17]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.asoc.2015.01.035"},{"key":"e_1_3_3_3_2","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1007\/978-3-319-19222-2_2","volume-title":"Advances in Computational Intelligence: 13th International Work-Conference on Artificial Neural Networks","author":"Bol\u00f3n-Canedo Ver\u00f3nica","year":"2015","unstructured":"Ver\u00f3nica Bol\u00f3n-Canedo, Noelia S\u00e1nchez-Maro\u00f1o, and Amparo Alonso-Betanzos. 2015.
