The leaky integrate-and-fire (LIF) model is one of the elementary neuronal models that has been widely used to gain understanding of the behavior of many excitable systems. The sinusoidally forced standard leaky integrate-and-fire model reproduces the quasiperiodic and phase locked discharge trains...

The case still remains challenging even if we use the simple leaky-integrate-and-fire (LIF) (Gerstner, Kistler, Naud, & Paninski, 2014) neuron model. To enhance the application accuracy of SNNs, the conventional spike timing dependent plasticity (STDP) unsupervised learning rule can be improved...
