如何有效地从头表记录电位中准确定位脑电源的真实活动位置是神经认知脑功能研究中的一个关键问题。该文从无性生殖的生物在自然界中优胜劣汰的进化模式中得到启发,设计了基于进化策略算法来进行源定位。我们采取组合变异和自适应变步长相结合的方式对特定的问题进行求解。在三层球模型上的仿真结果表明了该方法能有效的对脑电源进行定位。
How to accurately locate the real position of the brain power supply from the recording power of the watch is a key issue in the study of neuro-cognitive brain function. Inspired by the evolutionary model of asexual reproduction of the superior and the fittest in nature, this paper designed an algorithm based on evolutionary strategy to locate the source. We take the combination of variation and adaptive step-by-step approach to solve specific problems. The simulation results on the three-layer model show that the method can effectively locate the brain power source.
