中文简介:
在系统识别中,系统的输入和输出都可供观察者使用,并且寻求算法来识别该系统的假设模型的参数。在这里,我们提出了一种新的形式方法,用于识别神经回路中的树突处理,该神经回路由与尖峰神经元模型级联的线性树突处理滤波器组成。电路的输入是属于带限功能空间的模拟信号。输出是与尖峰序列相关联的时间序列。我们推导出一种识别树突处理滤波器的算法,并以任意精度重建其内核。
课程简介: In system identification both the input and the output of a system are available to an observer and an algorithm is sought to identify parameters of a hypothesized model of that system. Here we present a novel formal methodology for identifying dendritic processing in a neural circuit consisting of a linear dendritic processing filter in cascade with a spiking neuron model. The input to the circuit is an analog signal that belongs to the space of bandlimited functions. The output is a time sequence associated with the spike train. We derive an algorithm for identification of the dendritic processing filter and reconstruct its kernel with arbitrary precision.
关 键 词: 系统识别; 假设模型; 神经回路
