The spiking neural network (SNN) is the third generation of artificial neural networks. The transmission and expression of information in SNN are performed by spike trains, making the SNN have the advantages of high calculation speed and low power consumption. Recently, researchers have employed the...
FIF and LIF neuron behavior, idealized for illustration. Note that, in the second case, the threshold is never reached due to the leakage. Neurons may also have a refractory period during which they can accumulate but not fire. Source: Bryon Moyer/Semiconductor Engineering ...
Fig. 2. Illustration of the concept of Iterative Magnitude Pruning (IMP), Early-Bird (EB) ticket, and the proposed Early-Time (ET) ticket applied to EB ticket. Our ET ticket reduces search cost for winning tickets by using a smaller number of timesteps during the search process. Note, ...
(b) An illustration of SNNs trained with three different learning approaches, including synergistic learning between synaptic weights and spike thresholds and its two degenerate single-learning versions of synaptic learning and threshold learning. 图1:(a)时空反向传播示意图。在前馈路径中,每个脉冲神经元...
(a) Illustration of a biological neuron. A neuron receives pre-synaptic stimulus from dendrites, and synaptic integration occurs in soma. When a membrane voltage exceeds a threshold, a neuron generates an action potential, which is transmitted to other neurons through axon. (b,c) Neurotransmitter...

We used EventProp and a time-to-first-spike loss function to train a two-layer leaky integrate-and-fire network on the Yin-Yang dataset. (A) Illustration of the two-dimensional training dataset. The three different classes are shown in red, green and blue. This dataset was encoded using ...
Fig. 6: Estimating Dendrify’s performance for increasing network complexity and size. aSchematic illustration of the three model cases used for the scalability analysis. In all cases, the neuronal model was an adapted version of the four-compartment model shown in Fig.2a. Note that the number...
“Brian” is a popular Python-based simulator for spiking neural networks, commonly used in computational neuroscience. GeNN is a C++-based meta-compiler for accelerating spiking neural network simulations using consumer or high performance grade graphics processing units (GPUs). Here we introduce a ...
Apparatus and methods for heterosynaptic plasticity in a spiking neural network having multiple neurons configured to process sensory input. In one exemplary approach, a heterosynap
