摘要 传统基于核的最小均方误差(KMSE)算法在进行人脸识别时,需要求解多个方程,计算量较大。为此,提出一种用于多类识别的基于核的多元最小均方误差(KMSEMC)算法,该算法只需一个方程即可。在AR人脸库上的实验及数据分析表明,该算法在时间复杂度和识别率等方面计算量较小,在识别性能和计算时间上都优于同类传统算法。 The original Kernel-based minimum Mean Square Error(KMSE) algorithm,depends on a number of equations to address the multi-class classification problem,which causes a large computational afford.A new KMSE algorithm for Multi-class Kernel-based minimum Mean Square Error(KMSEMC) is proposed for multi-class recognization.It uses only one equation to do so,which is not only mathematically tractable but also computationally efficient.Experimental results on AR face databases show that KMSEMC outperforms KMSE in terms of computation and classification accuracy.
