Abstract (in Japanese) (See Japanese page) 
(in English) Person verification using evoked EEG by ultrasound has been studied.
From brain waves simultaneously measured at many electrodes, a spectral feature and several nonlinear features are extracted as individual features.
Using them, whether a user is genuine or not is verified by learning-based classifiers at each electrode.
Final decision is performed by the majority vote using the verified results of all features at all electrodes.
The verification error rate is reached to 0% but huge amount of time for learning many classifiers is required.
In this paper, it is confirmed that randomly selecting electrodes used in features makes possible to further reduce the number of classifiers.
The randomly-selecting is equivalent with evenly selecting electrodes for each feature and each electrode position.
The effectiveness of the evenly-selecting is statistically confirmed.
Furthermore, the evenly-selecting leads to fusing uncorrelated features.
Thus, four statistical values of brain waves are introduced and the effectiveness of fusing uncorrelated features is confirmed.
