In this paper, an efficient feature extraction algorithm called discriminant sparse local spline embedding (D-SLSE) is proposed for face recognition. A sparse neighborhood graph of the input data is firstly constructed based on a sparse representation framework, and then the low-dimensional embedding of the data is obtained by faithfully preserving the intrinsic geometry of the data samples based on such sparse neighborhood graph and best holding the discriminant power based on the class information of the input data. Finally, an orthogonalization procedure is perfomred to improve discriminant power. The experimental results on the two face image databases demonstrate that D-SLSE is effective for face recognition. © 2015 Elsevier B.V.

The grey synthetic relational analysis (GSRA) method-based effectiveness evaluation of the electronic warfare command and control (EWCC) system with incomplete information is investigated. The evaluation hierarchy structure of the EWCC system is put forward and classified into the target hierarchy, the rule hierarchy and the scheme hierarchy. Then, based on the analytic hierarchy process (AHP) method and the grey relational analysis (GRA) method, the GSRA method is given to evaluate the effectiveness evaluation of the EWCC system with incomplete information. Finally, an effectiveness evaluation example of three EWCC systems with incomplete information shows the effectiveness of the GSRA method. © (2014) Trans Tech Publications, Switzerland.
