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 ...

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

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
However, previously implemented artificial neurons, e.g., Hodgkin–Huxley (HH) neurons, integrate‐and‐fire (IF) neurons, and LIF neurons, only achieve partial functionality of a biological neuron. In this work, quasi‐HH neurons with leaky integrate‐and‐fire functions are physically ...
Further simulation results showed that Mott devices system has comparable features to that of an artificial neuron with the leaky integrate and fire functionality. The Mott device system developed by the way of the authors simulates basic functions of spiking neurons with the phenomenon of the...
