Higher-order tensor independent component analysis to realize MIMO remote sensing of respiration and heartbeat signals
Seishiro Goto, Ryo Natsuaki, Akira Hirose
This paper proposes a novel method of independent component analysis (ICA), which we name higher-order tensor ICA (HOT-ICA). HOT-ICA is a tensor ICA that makes effective use of the…

Complex-valued reservoir computing for aspect classification and slope-angle estimation with low computational cost and high resolution in interferometric synthetic aperture radar
Bungo Konishi, Akira Hirose, Ryo Natsuaki
Synthetic aperture radar (SAR) is widely used for ground surface classification since it utilizes information on vegetation and soil unavailable in optical observation. Image class…

Online regularization of complex-valued neural networks for structure optimization in wireless-communication channel prediction
Tianben Ding, Akira Hirose
This paper proposes online-learning complex-valued neural networks (CVNNs) to predict future channel states in fast-fading multipath mobile communications. CVNN is suitable for dea…
