脉冲神经网络的应用与优劣势 从理论上讲,SNNs可用于与标准ANNs相同的应用。目前,SNNs主要的应用领域还是在脑科学与认知科学中,用于了解生物动物的中枢神经系统,如昆虫在陌生环境中寻找食物。由于SNNs的相似性,它们可以被用来研究生物大脑网络的运作:从一个关于真实神经回路的拓扑结构和功能的假设开始,该回路的记录可以与...

Recently spiking neural networks (SNNs), the third-generation of neural networks has shown remarkable capabilities of energy-efficient computing, which is a promising alternative for deep neural networks (DNNs) with high energy consumption. SNNs have reached competitive results compared to DNNs in ...
Spiking neural networks (SNNs) are a type of neural network based around changes to an existing state. Spike-based approaches seek to more closely model the dynamics of learning in biological brains, with chains of signal spikes corresponding to incoming stimuli spread out over time. ...
脉冲神经网络Spiking neuralnetworks(SNNs)是第三代神经网络模型,其模拟神经元更加接近实际,除此之外,把时间信息的影响也考虑当中。思路是这种,动态神经网络中的神经元不是在每一次迭代传播中都被激活(而在典型的多层感知机网络中却是),而是在它的膜电位达到某一个特定值才被激活。当一个神经元被激活,它会产生一个...
Spiking Neural Networks (SNNs).SNN因构建低功耗智能而日益受到关注。通常,获得高性能的SNN算法可以分为两类:(1) ANN-SNN转换(Rueckauer et al., 2016; 2017; Han et al., 2020; Sengupta et al., 2019; Han & Roy, 2020)和 (2) 从头开始直接训练SNN (Wu et al., 2018; 2019)。基于转换的方法利...

Section 5 shows the results of using proposed spiking neural network to classify control chart patterns. Finally, Section 6 concludes the paper. 2. Spiking neural networks architecture Spiking neural networks (SNNs) have a similar architecture to traditional neural networks. Elements that differentiate ...
Similar to the brain, neurons in spiking neural networks (SNNs) communicate via short pulses called spikes that arrive in continuous time—in striking contrast to artificial neural networks (ANNs) where neurons communicate by the exchange of real-valued signals in discrete time. While ANNs are the...
尖峰时间依赖可塑性(STDP)是SNNs中最常用的学习算法之一[16]。这种受生物学启发的学习规则根据突触前和突触后尖峰的相对时间来修改突触强度(即权重)。由于加速器是为推理而设计的,因此本工作中没有报告学习过程的细节。用户可以自由决定能够达到期望目标的训练方法,例如准确性或生物学合理性。
