Herein, a diffusive CH3NH3PbI3(MAPbI3)-based memristor with superior amplitude-frequency characteristics and highly linear conductivity modulation for more than 1000 states have been fabricated for the construction of a leaky integrate-and-fire (LIF) bio-inspired neuron. The as-designed LIF model ...
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...
Parametric Leaky Integrate-and-Fire Neuron(PLIF) ① τm 在训练过程中自动优化 ② τm 在神经网络具体层上的神经元间是共享的 ③ τm 在神经网络不同层间是不同的(不同层的神经元具有不同的相频响应) 2. Training SNN as RNN SNN中的神经元能被看作是特殊的RNN中的结点:膜电位看作是RNN中的hidden ...
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 ...

Analysis of sinusoidal noisy leaky integrate-and-fire models and comparison with experimental data are important to understand the neural code and neural synchronization and rhythms. In this paper, we propose two methods to estimate input parameters using interspike interval data only. One is based on...

Spiking Neural Networks (SNNs) are valued for their ability to process spatio-temporal information efficiently, offering biological plausibility, low energy consumption, and compatibility with neuromorphic hardware. However, the commonly used Leaky Integrate-and-Fire (LIF) model overlooks neuron ...
