The strategy of one-against-all (OVA) was employed to decompose the multi-classification problem into a series of binary classification problems. The elastic net was used to select class-specific features for the binary classification problems, and the probabilistic support vector machine was used to make the outputs of the binary classifiers with class-specific features comparable. Simulation data and gene expression profile data were intended to verify the effectiveness of the proposed method. Results indicate that the proposed method can automatically select class-specific features and obtain better performance of classification than that of the conventional multi-class classification methods, which are mainly based on global feature selection methods. This study indicates the proposed method is suitable for general multi-classification problems featured with high-dimension, small samples, and collinear data.<\/jats:p>","DOI":"10.3390\/s20051528","type":"journal-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T11:59:36Z","timestamp":1583841576000},"page":"1528","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Using Class-Specific Feature Selection for Cancer Detection with Gene Expression Profile Data of Platelets"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5255-4687","authenticated-orcid":false,"given":"Lei-ming","family":"Yuan","sequence":"first","affiliation":[{"name":"College of Electrical &amp; Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiye","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Planning &amp; Finance, Wenzhou University, Wenzhou 325035, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangzao","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Electrical &amp; Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1038\/nrc.2017.7","article-title":"Liquid biopsies come of age: Towards implementation of circulating tumour DNA","volume":"17","author":"Wan","year":"2017","journal-title":"Nat.
