After research, it was found that the behavior of users on social networking sites has a great correlation with their personalities. The five characteristics of the OCEAN personality model can cover all aspects of a user\u2019s personality. In this research, a micro-directional propagation model based on the OCEAN personality model and a Stacked Denoising Auto Encoder (SDAE) was built through the application of deep learning to a collaborative filtering technique. Firstly, the dimension of the user and item feature matrices was lowered using SDAE in order to extract deeper information. The user OCEAN personality model matrix and the reduced user feature matrix were integrated to create a new user feature matrix. Finally, the multiple linear regression approach was used to predict user-unrated goods and generate recommendations. This approach allowed us to leverage the relationships between various factors to deliver personalized recommendations. This experiment evaluated the RMSE and MAE of the model. The evaluation results show that the stacked denoising auto encoder collaborative filtering algorithm can improve the accuracy of recommendations, and the user\u2019s OCEAN personality model improves the accuracy of the model to a certain extent.<\/jats:p>","DOI":"10.3390\/systems12060188","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T05:14:02Z","timestamp":1716786842000},"page":"188","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Stacked Noise Reduction Auto Encoder\u2013OCEAN: A Novel Personalized Recommendation Model Enhanced"],"prefix":"10.3390","volume":"12","author":[{"given":"Bixi","family":"Wang","sequence":"first","affiliation":[{"name":"The Faculty of Education, Shaanxi Normal University, Xi\u2019an 710063, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8486-1654","authenticated-orcid":false,"given":"Wenfeng","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Automation, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"given":"Ruiyang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Automation, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"given":"Siyu","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Automation, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5022-610X","authenticated-orcid":false,"given":"Lirong","family":"Yin","sequence":"additional","affiliation":[{"name":"Department of Geography and Anthropology, Louisiana State University, Baton Rouge, LA 70803, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1298-4839","authenticated-orcid":false,"given":"Lei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Geography and Anthropology, Louisiana State University, Baton Rouge, LA 70803, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9818-9205","authenticated-orcid":false,"given":"Zhengtong","family":"Yin","sequence":"additional","affiliation":[{"name":"College of Resource and Environment Engineering, Guizhou University, Guiyang 550025, China"}]},{"given":"Xinbing","family":"Chen","sequence":"additional","affiliation":[{"name":"The Faculty of Education, Shaanxi Normal University, Xi\u2019an 710063, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,26]]},"container-title":["Systems"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mdpi.com\/2079-8954\/12\/6\/188\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T14:49:08Z","timestamp":1760107748000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.mdpi.com\/2079-8954\/12\/6\/188"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,5,26]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2024,6]]}},"alternative-id":["systems12060188"],"URL":"https:\/\/doi.org\/10.3390\/systems12060188","relation":{},"ISSN":["2079-8954"],"issn-type":[{"value":"2079-8954","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,5,26]]}}}
