Margin Emphasized Metric Learning and Its Application to Gabor Feature Based Face Recognition
face verification metric learning margin Gabor Labeled Faces in Wild
2013/7/24
In addressing side information based face recognition scenario, a new Margin Emphasized Metric Learning (MEML) method is proposed. As an improvement of previous metric learning, MEML defines a new obj...
基于不同Margin的人脸特征选择及识别方法
人脸识别 Margin 特征选择 支持向量机(SVM) 顺序后退法(SBS)
2008/6/6
Margin在机器学习中具有很重要的意义，基于margin的特征选择方法就是从分类的角度对特征集各特征的权重进行分析。该文对不同的margin进行了分析，提出将sample-margin和hypothesis-margin分别作为特征选择标准对SBS特征选择方法进行改进，然后设计具有最佳超参数的SVM多项式分类器进行人脸识别。实验在FRERT人脸图像库上进行并与Relief特征选择方法进行了比较，...
