摘要
建立了一种基于皮层柱侧抑制机制的神经网络群,模拟大脑皮层柱的神经元点火现象,并利用该神经网络群进行位置跟踪.采用Stein神经元构建神经网络群;将皮层柱的侧抑制机制应用于神经网络群编码、解码,实现神经网络群的负相关点火,并从理论上证明负相关点火的优越性.仿真实验结果表明,皮层柱侧抑制机制的应用大大提高了位置跟踪精度以及系统稳定性.
The neural network ensembles based on lateral inhibition of cortical columns are built to simulate the neuron firing phenomenon in cortical columns and to be used for position tracking. The neural network ensembles are composed of many Stein＇s neurons. Lateral inhibition of cortical columns is applied to the coding and decoding of neural network ensembles to realize the negatively correlated firing, and the advantages of the negatively correlated firing are proved theoretically. Simulation results show＇ that the application of lateral inhibition with cortical columns can greatly improve the position tracking accuracy and system stability.
