Embodiment 1
[0041] This embodiment discloses a method for constructing an evolvable spiking neural network, including:
[0042] Step 1: Initialize the evolvable spiking neural network;
[0043] Specifically, the neural network includes an input layer, a supervisory neuron and an output layer; the maximum number of output neurons of the network is set, and the number of output types is determined according to the input training samples; and other parameters in the evolvable spiking neural network are initialized at the same time.
[0044] Such as figure 1 As shown, the structure is divided into input layer, supervisory neuron and output layer, and the input of spiking neural network is x={x 1 ,...,x i ,...,x m}, the output is Y={Y 1 ,...,Y j ,...,Y k}, the supervisory neuron is located between the input layer and the output layer, and is used to update the network weights according to the existing characteristics of the network. The supervisory neuron provides a correction parameter...
