Learning multi-kernel multi-view canonical correlations for image recognition

In this paper, we propose a multi-kernel multi-view canonical correlations(M2CCs) framework for subspace learning. In the proposed framework,the input data of each original view are mapped into multiple higher dimensional feature spaces by multiple nonlinear mappings determined by different kernels. This makes M2 CC can discover multiple kinds of useful information of each original view in the feature spaces. With the framework, we further provide a specific multi-view feature learning method based on direct summation kernel strategy and its regularized version. The experimental results in visual recognition tasks demonstrate the effectiveness and robustness of the proposed method.
