Published Papers
Hideki Tamura, Hiroshi Higashi, Shigeki Nakauchi
Scientific Reports 8 Dec 2018 [Refereed]
© 2018 The Author(s). Mirror materials (perfect specular surfaces such as polished metal) and glass materials (transparent and refraction media) are quite commonly encountered in everyday life. The human visual system can discriminate these comple...

Frontiers in Human Neuroscience 11 Feb 2017 [Refereed]
© 2017 Higashi, Minami and Nakauchi. The probability of an event’s occurrence affects event-related potentials (ERPs) on electroencephalograms. The relation between probability and potentials has been discussed by using a quantity called surprise ...

IEEE Journal on Selected Topics in Signal Processing 10(7) 1305 Oct 2016 [Refereed]
© 2016 IEEE.The classification accuracy of a brain-computer interface (BCI) frequently suffers from ill-posed and overfitting problems. To avoid and alleviate these problems, we propose a method of a multilinear discriminant analysis with constrai...

IEEE Transactions on Biomedical Engineering 62(2) 458-467 Feb 2015 [Refereed]
© 2014 IEEE. Rejecting or selecting data from multiple trials of electroencephalography (EEG) recordings is crucial. We propose a sparsity-aware method to data selection from a set of multiple EEG recordings during motor-imagery tasks, aiming at b...

IEEE Transactions on Biomedical Engineering 60(10) 2831-2838 Sep 2013 [Refereed]
A brain-computer interface (BCI) based on steady-state visual-evoked potentials (SSVEP) has two difficulties: limitation of the number of commands and uneven probabilities of command execution. To address these problems, the present paper proposes...

IEEE Transactions on Biomedical Engineering 60(4) 1100-1110 Apr 2013 [Refereed]
The spatial weights for electrodes called common spatial pattern (CSP) are known to be effective in EEG signal classification for motor imagery-based brain-computer interface (MI-BCI). To achieve accurate classification in CSP, it is necessary to ...
