A novel method that integrates brain activity-based classifications obtained from multiple users is presented in this paper. The proposed method performs decision-level fusion (DLF) of the classifications using a kernelized version of extended supervised learning from multiple experts (KESLME), which is newly derived in this paper. In this approach, feature-level fusion of multiuser electroencephalogram (EEG) features is performed by multiset supervised locality preserving canonical correlation analysis (MSLPCCA). In the proposed method, the multiple classification results are obtained by classifiers separately constructed for the multiuser EEG features. Then DLF of these classification results becomes feasible based on KESLME, which can provide the final decision with consideration of the relationship between the MSLPCCA-based integrated EEG features and each classifier's performance. In this way, a new multi-classifier decision technique, which depends only on users' brain activities, is realized, and the performance in an image classification task becomes comparable to that of Inception-v3, one of the state-of-the-art deep convolutional neural networks.
