Keeping this as background, this study proposes an anomaly detection algorithm (VAEOCSVM), which combines the variable auto-encoder (VAE) and one-class support vector machine (OCSVM) to realize anomaly detection in industrial control networks. First, the VAE model is used to obtain the distribution of the original normal sample data represented by the low-dimensional code; the reconstruction error of the VAE model is merged into the new input. Then, using OCSVM\u2019s hinge-loss objective function and the random Fourier feature fitting radial basis function (RBF) kernel method, the OCSVM model is represented and solved using the deep neural network and gradient descent method. Finally, the decision function of the OCSVM model is constructed by using the solved parameter information to realize the detection of abnormal data. The proposed algorithm is compared with other machine-learning-based anomaly detection algorithms in terms of multiple indicators such as precision, recall, and [Formula: see text] score. The experimental results using various datasets show that the proposed algorithm has a better outlier recognition ability than the machine-learning-based anomaly detection algorithms.<\/jats:p>","DOI":"10.1142\/s0218001421500129","type":"journal-article","created":{"date-parts":[[2020,9,14]],"date-time":"2020-09-14T03:01:25Z","timestamp":1600052485000},"page":"2150012","source":"Crossref","is-referenced-by-count":5,"title":["Anomaly Detection for Industrial Control Networks Based on Improved One-Class Support Vector Machine"],"prefix":"10.1142","volume":"35","author":[{"given":"Haicheng","family":"Qu","sequence":"first","affiliation":[{"name":"Institute of Software, Liaoning Technical University, Huludao 125105, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5476-5883","authenticated-orcid":false,"given":"Jianzhong","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Software, Liaoning Technical University, Huludao 125105, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jitao","family":"Qin","sequence":"additional","affiliation":[{"name":"Institute of Software, Liaoning Technical University, Huludao 125105, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaorong","family":"Tian","sequence":"additional","affiliation":[{"name":"Institute of Software, Liaoning Technical University, Huludao 125105, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,12,16]]},"reference":[{"key":"S0218001421500129BIB001","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1007\/978-3-319-14142-8_8","volume-title":"Data Mining","author":"Aggarwal C.","year":"2015"},{"key":"S0218001421500129BIB002","doi-asserted-by":"publisher","DOI":"10.1145\/2500853.2500857"},{"key":"S0218001421500129BIB004","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-25237-2_2"},{"key":"S0218001421500129BIB005","first-page":"3743","volume-title":"Proc. 31st Int.
