摘要

摘要: 典型相关分析(CCA)作为一种经典的特征融合方法，广泛用于模式识别领域，其目标是学习相关投影方向使两组变量间的相关性最大，但其没有考虑样本的类标签信息和样本间的信息冗余(MDOCCA)，从而影响了融合后特征的监督敏感性和鉴别力。为此，该文提出一种标签敏感的多重集正交相关特征融合方法，该方法在典型相关分析理论基础上，将类标签信息嵌入到特征融合框架，同时加入正交约束确保融合特征最大限度的不相关，减少特征信息冗余，提高鉴别力。在不同图像数据集上的实验结果显示该方法是一种有效的特征融合方法。

Abstract: As a classic feature fusion method, Canonical Correlation Analysis (CCA) is widely used in the field of pattern recognition. Its goal is to learn the relevant projection direction to maximize the correlation between the two sets of variables, but the class label information of the sample and the information between samples redundancy are not considered, which affects the supervisory sensitivity and discriminative power of the fused features. To this end, a label-sensitive Multi-set Discriminant Orthogonal Canonical Correlation Analysis (MDOCCA) feature fusion method is proposed. This method is based on canonical correlation analysis theory. The class label information is embedded into the feature fusion framework, and the orthogonal constraint is added to ensure the maximum fusion of features. Irrelevant, the redundancy of feature information is reduced and the discrimination is improved. Some experiments on multiple image data sets show that this method is an effective feature fusion method.
