Brain-computer interface (BCI) is a new type of man-machine interfaces and one of the key technologies of rehabilitation robot. In this paper, the BCI system structure, working principle and the key technology are discussed. The dummy matrix based on event-related potential P300 is designed, used the stimulation by the character matrix sequence, subjects(More)
In the paper, a vehicle recognition model based on least squares support vector machine(LSSVM) is presented. LSSVM can solve the problem of nonlinear well, avoiding some difficulties including high dimensional and local minimum. In the model, the non-sensitive loss function is replaced by quadratic loss function and the inequality constraints are replaced(More)
