Traditional ERP-based BCI systems may perform poorly for small training samples, i.e. the undersampling problem. In this study, the ERP classification problem was investigated, in particular, the ERP classification in the high-dimensional setting with the number of features larger than the number of samples was studied. A flexible group sparse discriminative analysis algorithm based on Moreau\u2013Yosida regularization was proposed for alleviating the undersampling problem. An optimization problem with the group sparse criterion was presented, and the optimal solution was proposed by using the regularized optimal scoring method. During the alternating iteration procedure, the feature selection and classification were performed simultaneously. Two P300-based BCI datasets were used to evaluate our proposed new method and compare it with existing standard methods. The experimental results indicated that the features extracted via our proposed method are efficient and provide an overall better P300 classification accuracy compared with several state-of-the-art methods. <\/jats:p>","DOI":"10.1142\/s0129065719500023","type":"journal-article","created":{"date-parts":[[2019,1,15]],"date-time":"2019-01-15T06:07:45Z","timestamp":1547532465000},"page":"1950002","source":"Crossref","is-referenced-by-count":35,"title":["Regularized Group Sparse Discriminant Analysis for P300-Based Brain\u2013Computer Interface"],"prefix":"10.1142","volume":"29","author":[{"given":"Qiang","family":"Wu","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Shandong University, Jinan, Shandong, P.
