This study presents an algorithm for multi-channel electroencephalographic (EEG) spike prescreening based on radial basis function (RBF) artificial neural network. Sixteen-channel EEG records from twenty-eight patients with epilepsy were examined online. The single-channel recognition network consisted of input-layer neurons receiving three EEG waveform parameters (peak angle, amplitude, and velocity), ten hidden-layer neurons, and one output neuron. An optimal network model was chosen according to receiver operating characteristics analysis. Identification of multi-channel geometric correlation was performed with an incidence matrix. Sensitivity and selectivity cross-over value was found to be 80% for the single-channel RBF network. Compared with error back-propagation, a substantial improvement in training efficiency by at least two to three orders of magnitude was obtained for the RBF network. Validation with visual analysis showed 87.3% sensitivity using the proposed online multi-channel classification algorithm. The computation time required for spike detection was significantly less than that needed for online display of the EEG record. The proposed algorithm was able to achieve classification accuracy similar to previous artificial neural network schemes based on error back-propagation, while the training needed for RBF network was substantially less. Therefore, the RBF neural network is potentially an effective tool in real-time prescreening for epileptic spikes.

This paper Investigates Hamiltonian realization of time-varying nonlinear (TVN) systems, and proposes a number of new methods for the problem. It is shown that every smooth TVN system can be expressed as a generalized Hamiltonian system if the origin is the equilibrium of the system. If the Jacooian matrix of a TVN system is nonsingular, the system has a generalized Hamiltonian realization whose structural matrix and Hamiltonian function are given explicitly. For the case that the Jacobian matrix is sin- gular; this paper provides a constructive decomposition method, and then proves that a TVN system has a generalized Hamiltonian realization if its Jacobian matrix has a non- singular main diagonal block. Furthermore, some sufficient (necessary and sufficient) conditions for dissipative Hamiltonian realization of TVN systems are also presented in this paper.
Agent-based models are widely used for the simulation of systems from several domains (biology, economics, meteorology, etc). In biology agent-based models are very useful for predicting the social behaviour of system...
