Federated learning is a new distributed machine learning paradigm, in which system heterogeneity is the difficulty of fairness design. This paper designs a system heterogeneous fair federated learning algorithm (SHFF). SHFF introduces the equipment influence factor I into the optimization target and dynamically adjusts the equipment proportion with other performance. By changing the global fairness parameter \u03b8, the algorithm can control fairness according to the actual needs. Experimental results show that, compared with the popular q-FedAvg algorithm, the SHFF algorithm proposed in this paper improves the average accuracy of the Worst 10% by 26% and reduces the variance by 61%.<\/jats:p>","DOI":"10.3233\/jcm-214991","type":"journal-article","created":{"date-parts":[[2021,4,20]],"date-time":"2021-04-20T23:36:38Z","timestamp":1618961798000},"page":"1365-1373","source":"Crossref","is-referenced-by-count":4,"title":["Heterogeneous fairness algorithm based on federated learning in intelligent transportation system"],"prefix":"10.66113","volume":"21","author":[{"given":"Yue","family":"Jiang","sequence":"first","affiliation":[{"name":"College of Computer Science and Technology, Jilin University, Changchun, Jilin 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaochao","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Jilin University, Changchun, Jilin 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyi","family":"Fang","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Jilin University, Changchun, Jilin 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinan","family":"Song","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Jilin University, Changchun, Jilin 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingbing","family":"Li","sequence":"additional","affiliation":[{"name":"JiLin Business and Technology College, Changchun, Jilin 130000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55691","reference":[{"key":"10.3233\/JCM-214991_ref1","doi-asserted-by":"crossref","unstructured":"S.
