We propose a face recognition method named the Laplacian+OPRA-faces approach based on the Laplacian-faces and the OPRA-faces approach. An explicit mapping from the high-dimensional data space to the reduced space is obtained. The method aims to preserve both the local structure of local preserving projections (LLE) and the local geometry of orthogonal(More)

How to recognize SSVEP with(More)
A decentralized unscented Kalman filter (UKF) method based on a consensus algorithm for multi-area power system dynamic state estimation is presented in this paper. The overall system is split into a certain number of non-overlapping areas. Firstly, each area executes its own dynamic state estimation based on local measurements by using the UKF. Next, the(More)
OBJECTIVE Daytime short nap involves individual physiological states including alertness and drowsiness. In order to have a better understanding of the periodical rhymes of physiological states and then promote a good interpretability of alertness, the aim of this study is to detect drowsiness during daytime short nap. METHODS A method of Bayesian-copula(More)
