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…
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...

Leaky Integrate-and-Fire Modelsdoi:10.1007/978-3-540-29678-2_2736Leaky integrate and fire models represent a specific type of connectionist networks (artificial neural networks) which incorporate real-time dynamics. Unit activation is computed according to a......
progressing to more generalized leaky integrate-and-fire models. In the standard LIF model (GLIF1here), current injected into the cell causes the voltage to rise in a linear fashion. When the voltage reaches a fixed threshold (referred to as Θ∞here) the model spikes and the threshold is ...
We introduce an ultra-compact electronic circuit that realizes the leaky-integrate-and-fire model of artificial neurons. Our circuit has only three active devices, two transistors and a silicon controlled rectifier (SCR). We demonstrate the implementatio

Leaky Integrate-and-Fire神经元模型——在这种划分的中间位置有一个Leaky Integrate-and-Fire (LIF)神经元模型。它需要加权输入的和,很像人工神经元。但它不是将其直接传递给激活函数,而是随着时间的推移将输入与泄漏集成,很像RC电路。如果积分值超过阈值,则LIF神经元将发射电压峰。LIF神经元抽象出输出脉冲的形状和...
However, the commonly used Leaky Integrate-and-Fire (LIF) model overlooks neuron heterogeneity and independently processes spatial and temporal information, limiting the expressive power of SNNs. In this paper, we propose the Dual Adaptive Leaky Integrate-and-Fire (DA-LIF) model, which introduces ...
