Abstract: In this paper, we present supervised fractional-order embedding multiview canonical correlation analysis (SFEMCCA). SFEMCCA is a CCA method realizing the following three points: (1) learning noisy data with small number of samples and large number of dimensions, (2) multiview learning that can integrate three or more kinds of features, and (3) supervised learning using labels corresponding to the samples. In real data, it is necessary to deal with high dimensional noisy data with limited number of samples, and there are many cases where three or more kinds of multimodal and supervised data are treated in order to calculate more accurate projections. Therefore, SFEMCCA, which takes the above advantages (1)-(3) into account, is effective for data obtained from real environments. From experimental results, it was confirmed that accuracy improvements using SFEMCCA were statistically significant compared to the several conventional methods of supervised multiview CCA.
