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...
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, ...
The network receives, in addition to the input x(t), a delayed target feedback signal \(y(t-\tau )\), and produces the output \({\hat{y}}(t)\) (where y(t) is the actual target). (B) Illustration of the two-link arm model with states given by the angle of the links, ...
(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...
Figure 5. Neural activity fitting experiments (A) Graphical illustration of the simple neural activity fitting experiment: spiking neural models were optimized to produce spike outputs close to the recorded neural activities. (B) The average firing rate Pearson correlation coefficients of different fittin...
Equation (4) is an illustration of how complementary superposition information encoding works, with no factual significance. In this work, we focus on quantum image superposition encoding, as in Equation (5). However, it should be noted that any form of information that has a complement format,...
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. ...
(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...
