At present, back propagation (BP) neural network and particle swarm optimization algorithm can be well combined with feature selection. On this basis, this paper adds interference factors to BP neural network and particle swarm optimization algorithm to improve the accuracy and practicability of feature selection. This paper summarizes the basic methods and requirements for feature selection and combines the benefits of global optimization with the feedback mechanism of BP neural networks to feature based on backpropagation and particle swarm optimization (BP-PSO). Firstly, a chaotic model is introduced to increase the diversity of particles in the initial process of particle swarm optimization, and an adaptive factor is introduced to enhance the global search ability of the algorithm. Then, the number of features is optimized to reduce the number of features on the basis of ensuring the accuracy of feature selection. Finally, different data sets are introduced to test the accuracy of feature selection, and the evaluation mechanisms of encapsulation mode and filtering mode are used to verify the practicability of the model. The results show that the average accuracy of BP-PSO is 8.65% higher than the suboptimal NDFs model in different data sets, and the performance of BP-PSO is 2.31% to 18.62% higher than the benchmark method in all data sets. It shows that BP-PSO can select more distinguishing feature subsets, which verifies the accuracy and practicability of this model.<\/jats:p>","DOI":"10.1155\/2021\/6715564","type":"journal-article","created":{"date-parts":[[2021,6,1]],"date-time":"2021-06-01T20:31:12Z","timestamp":1622579472000},"page":"1-11","source":"Crossref","is-referenced-by-count":2,"title":["Feature Selection Based on BP Neural Network and Adaptive Particle Swarm Algorithm"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0095-5881","authenticated-orcid":true,"given":"Bingsheng","family":"Chen","sequence":"first","affiliation":[{"name":"College of Physics and Electronic Information, Gannan Normal University, Ganzhou 341000, Jiangxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huijie","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Physics and Electronic Information, Gannan Normal University, Ganzhou 341000, Jiangxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengshan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Physics and Electronic Information, Gannan Normal University, Ganzhou 341000, Jiangxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1002\/spe.2834"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2019.02.030"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/s00500-016-2474-6"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2018.04.062"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.nucengdes.2017.11.006"},{"issue":"1","key":"6","first-page":"42","article-title":"Multi-objective test case prioritization based on multi-population cooperative particle swarm optimization","volume":"27","author":"Wang","year":"2020","journal-title":"The Journal of China Universities of Posts and Telecommunications"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jctc.9b00880"},{"issue":"9","key":"8","first-page":"11","article-title":"A new intrusion detection system based on Fast Learning Network and Particle swarm optimization","volume":"5","author":"M.
