Our proposed method incorporated two tasks in an automatic expression analysis system: facial feature extraction and classification into expressions. To obtain local and geometric structure information in the data as much as possible, we unite max-margin classification into the constrained NMF optimization, resulting in a multiplicative updating algorithm is also proposed for solving optimization problem. Experimental results on JAFFE dataset demonstrate that the effectiveness of the proposed method with improved performances over the conventional dimension reduction methods. 2021-03-01T09:24:54Z 2021-03-01T09:24:54Z 2019 Working Paper http://elib.vku.udn.vn/handle/123456789/960 en application/pdf Da Nang Publishing House |
