Thus, it is critically important to identify whether proteins themselves interact with each other. Although there are some existing experimental methods for self-interaction recognition, the limitations of these methods are both expensive and time-consuming. Therefore, it is very necessary to develop an efficient and stable computational method for predicting SIPs. In this study, we develop an effective computational method for predicting SIPs based on rotation forest (RF) classifier, combined with histogram of oriented gradients (HOG) and synthetic minority oversampling technique (SMOTE). When performing SIPs prediction on yeast and human datasets, the proposed method achieves superior accuracies of 97.28% and 89.41%, respectively. In addition, the proposed approach was compared with the state-of-the-art support vector machine (SVM) classifiers and other different methods on the same datasets. The experimental results demonstrate that our method has good robustness and effectiveness and can be regarded as a useful tool for SIPs prediction.<\/jats:p>","DOI":"10.1155\/2021\/6677758","type":"journal-article","created":{"date-parts":[[2021,3,10]],"date-time":"2021-03-10T22:20:07Z","timestamp":1615414807000},"page":"1-10","source":"Crossref","is-referenced-by-count":1,"title":["Self-Interacting Proteins Prediction from PSSM Based on Evolutionary Information"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3343-1531","authenticated-orcid":true,"given":"Zheng","family":"Wang","sequence":"first","affiliation":[{"name":"School of Information Engineering, Xijing University, Xi\u2019an 710123, China"}]},{"given":"Yang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Xijing University, Xi\u2019an 710123, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7785-929X","authenticated-orcid":true,"given":"Li-Ping","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Xijing University, Xi\u2019an 710123, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7373-7922","authenticated-orcid":true,"given":"Zhu-Hong","family":"You","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Xijing University, Xi\u2019an 710123, China"}]},{"given":"Wen-Zhun","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Xijing University, Xi\u2019an 710123, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.21769\/bioprotoc.2687"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemolab.2019.06.003"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2148-10-160"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.2174\/0929866527666191227141713"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1177\/1176934320924674"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2018.02.097"},{"key":"7","first-page":"164","article-title":"Protein-protein interactions prediction based on Bi-directional gated recurrent unit and multimodal representation","author":"K.
