According to the method, initialization of the pulse neural network is meta-learned by introducing an excitation-suppression balance mechanism constrained by the Deler law, and internal representation widely applicable to many small sample tasks is constructed. In order to ensure that the Thevener's law is strictly obeyed in the synaptic weight updating process, an improved projection gradient descent method is combined with synaptic plasticity, so that the nervous excitability and inhibition characteristics are kept unchanged. According to the invention, an excitation-suppression balance mechanism constrained by the Devener's law is introduced into pulse element learning, and a small sample pulse element learning method based on excitation-suppression balance under the constraint of the Devener's law is provided. In order to enhance the stability and generalization of pulse element learning, a multi-step weighted loss strategy is further developed to guide the element learning of the pulse neural network. The small sample pulse element learning method based on excitation-suppression balance under the constraint of the Devener's law is superior to an early element learning method based on an artificial neural network in some specific tasks, and is completely superior to MAML of a pulse version.
