Spiking neural network (SNN) is considered to be the brain-like model that best conforms to the biological mechanism of the brain. Due to the non-differentiability of the spike. the training method of SNNs is still incomplete. This paper proposes a supervised learning method for SNNs based on associative learning: ALSA. https://www.getpureroutine.com/mega-deal-natio-celebrate-eyeshadow-palette-online-amazing-offer/
