2011 Pattern Recognition Letters  
In this study, a new strategy for reducing LDA to Hotelling's canonical correlation analysis (CCA) is proposed.  ...  CCA seeks prominently correlated projections between two views of data and it has been long known to be equivalent to LDA when the data features are used in one view and the class labels are used in the  ...  Canonical correlation analysis (CCA) Canonical correlation analysis (CCA) is introduced by Hotelling (1936) to describe the linear relation between two multidimen-sional (or two sets of) variables as the  ...

Audiovisual Synchronization and Fusion Using Canonical Correlation Analysis

M.E. Sargin, Y. Yemez, E. Erzin, A.M. Tekalp
2007 IEEE transactions on multimedia  
In this paper, we propose a new multimodal fusion strategy for open-set speaker identification using a combination of early and late integration following canonical correlation analysis (CCA) of speech  ...  We note that the proposed fusion strategy outperforms others because the features used in the late integration are truly uncorrelated, since they are output of the CCA analysis.  ...  We propose using the canonical correlation analysis (CCA) to achieve synchronization (see Appendix for a brief review of the canonical correlation analysis).  ...
