- 报告摘要：
- Canonical correlation analysis (CCA) has proven an effective tool for two-view dimension reduction due to its profound theoretical foundation and success in practical applications. In respect of multi-view learning, however, it is limited by its capability of only handling data represented by two-view features, while in many real-world applications, the number of views is frequently many more. Although the ad hoc way of simultaneously exploring all possible pairs of features can numerically deal with multi-view data, it ignores the high order statistics (correlation information) which can only be discovered by simultaneously exploring all features. Therefore, We develop tensor CCA (TCCA) which straightforwardly yet naturally generalizes CCA to handle the data of an arbitrary number of views by analyzing the covariance tensor of the different views. As a consequence, the high-order correlation information contained in the different views is explored and thus a reliable common subspace shared by all features can be obtained. In addition to multi-view dimension reduction, we also apply TCCA to heterogeneous transfer metric learning by combining side information and unlabeled data. By maximizing the high-order correlation between all domains, much more correlation information can be encoded in the learned metrics, and hopefully better performance can be achieved.
