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 ...
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(...
The leaky integrate and fire (LIF) neuron represents standard neuronal model used for numerical simulations. The leakage is implemented in the model as exponential decay of trans-membrane voltage towards its resting value. This makes inevitable the usage of machine floating point numbers in the ...
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 ...

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
A sweet-spot choice for SNNs which compete with ANNs is that of the leaky integrate-and-fire (LIF) neuron, first studied in 1907 using biological systems23,24. This neuron is a popular choice for highly performant SNNs, due to its balance of simplicity and efficiency while being able to ...

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...
