Leaky Integrate-and-Fire LIF模型,顾名思义,包含了以下三大特征: Leaky:存在欧姆漏电流。 Integrate:一个能积累电流的部件,电容。 Fire:当输入电流足够大的时候,膜电压会产生突变(spiking) 它的线性微分方程表达式如下: CdVmdt=I−gleak(Vm−Eleak) 由方程易得LIF模型有这样的性质 存在明确的临界电压 Vthr...
神经元的交流,传输与活动,都离不开一个个非常短暂的脉冲-Spike。有各种各样的模型,可以描述神经元的电位变化,发放,比如HH模型等等。但是如果只考虑比较粗糙的一些性质,比如膜电位的简单变化和spike的频率之…

This paper investigates SNN employing a leaky integrate-and-fire neuron model with latency estimation through FNS. A three-layer feedforward network (FFN) is constructed, incorporating design parameters from Config Wizard. Notably, our study sheds light on the impact of synchrony within a simple ...
白话脉冲神经网络（3）：理解LIF（Leaky Integrate and Fire）神经元模型 神经元模型的世界多种多样，从复杂的生物模型到简单的数学抽象。LIF神经元，介于生物物理与人工神经元之间，以其平衡的生物合理性与计算效率吸引着研究者。它像人工神经元一样，通过加权输入，但不是直接激活，而是通过时间积分与泄漏...
