Definition and explanation of Spiking Neural Networks (SNNs)

Spiking Neural Networks (SNNs) are a class of artificial neural networks (ANNs) that are biologically inspired by the functioning of the human brain. Unlike traditional ANNs, which use continuous-valued signals as inputs and outputs, SNNs simulate the behavior of real neurons by emitting discrete electrical pulses, or spikes. These spikes are a fundamental property of neural communication in biological systems. In an SNN, information is encoded in the timing and frequency of these spikes, allowing for more efficient communication and representation of data. The neurons in an SNN are typically organized in layers, where each neuron receives inputs from its predecessors, and emits spikes according to certain activation functions. The output of an SNN is then decoded from the spiking activity of the output neurons. SNNs have the potential to overcome the limitations of traditional ANNs by better capturing the dynamics and information processing capabilities of the brain. They have applications in various fields, such as robotics, pattern recognition, and cognitive computing. However, the training of SNNs remains a challenge, as conventional gradient-based methods are not directly applicable, given the discrete nature of spikes.
