当电流达到Rheobase的时候,神经元开始放电,并且随着电流的增大放电频率呈对数型增加。 本文介绍了Linear Integrate-and-Fire Neuron模型,其实对应的还有non-linear模型,这里就不赘述了,感兴趣的读者可以自行搜集资料。 参考资料: MIT 9.40 Introduction to Neural Computation Lecture Note from Theoretical Biophysics and C...
In this work, we\nintroduce a low-powered neuron model called Integrate-and-Fire which exploits\nthe charge and discharge properties of the capacitor. Using parallel and series\nRC circuits, we developed a trainable neuron model that can be expressed in a\nrecurrent form. Finally, we trained ...
The Leaky Integrate-and-fire Neuron
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 Integrate-and-Fire Model The integrate-and-fire neuron is one of the simplest models of a neuron’s electrical properties and probably the most commonly used in the field of neuroscience. The essence of the model is to divide the voltage changes of the neuron into two parts: 1) Below...
