WebSep 9, 2024 · In this paper, we propose an L1-norm two-dimensional linear discriminant analysis (L1-2DLDA) with robust performance. Different from the conventional two-dimensional linear discriminant analysis ... WebSep 1, 2024 · By applying L 1-norm distance metric in the objective 2DPCA, Li et al. [26] proposed L 1-norm based 2DPCA (2DPCA-L1). In [27], a sparse version of 2DPCA-L1 (2DPCAL1-S) is developed. In addition to measuring the variance of data using L 1-norm distance metric, the solution is also imposed by L 1-norm. A common point of both …
