这是一篇很久前arXiv preprint上的文章,主要的思路是把常规SNN模型中的膜电位衰减因子从手动调节的超参数转换成模型能够学习的参数。 Proposed Methods Parametric Leaky Integrate-and-Fire Neuron(PLIF) ①τm在训练过程中自动优化 ②τm在神经网络具体层上的神经元间是共享的 ③τm在神经网络不同层间是不同的(...
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 ...
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Vthresh...
Neuro-biology inspired Spiking Neural Network (SNN) enables efficient learning and recognition tasks. To achieve a large scale network akin to biology, a power and area efficient electronic neuron is essential. Earlier, we had demonstrated an LIF neuron

The artificial spiking neural network (SNN) is promising and has been brought to the notice of the theoretical neuroscience and neuromorphic engineering research communities. In this light, we propose a new type of artificial spiking neuron based on leaky integrate-and-fire (LIF) behavior. A disti...

在下一部分中,我们将讨论leaky Fire-and-Integrate (LIF) 模型。 LIF模型基本上扩展了上面所示的对神经元建模的思想,但它确实带有一种新的味道:当膜电位达到某个阈值时,它会返回到一个较低的“重置”值。这本质上就是神经元被“激活”和释放尖峰的方式。
