Embodiment 1
[0038] Such as figure 1 As shown, this embodiment provides a second-order hybrid construction method of a complex-valued feedforward neural network, including the following steps: Step S1: initialize the structure and parameters of the complex-valued neural network according to a given task; Step S2: use The complex-valued second-order hybrid optimization algorithm adjusts the parameters in the complex-valued neural network, and judges whether the construction termination condition is satisfied. If not, proceed to step S3, and if satisfied, proceed to step S4; step S3: verify the complex-valued neural network The generalization performance of the network, saving the number of current hidden layer neurons and all parameter values of the complex-valued neural network, judging whether the addition criteria of the hidden layer neurons are met, and if so, using the complex-valued incremental construction mechanism , add a hidden layer neuron to the current model, calculate the ne...
Embodiment 2
[0098] Based on the same inventive concept, this embodiment provides a second-order hybrid construction system of a complex-valued feedforward neural network, and its problem-solving principle is similar to the second-order hybrid construction method of the complex-valued feedforward neural network. No longer.
[0099] This embodiment provides a second-order hybrid construction system of a complex-valued forward neural network, including:
[0100] The initialization module is used to initialize the structure and parameters of the complex-valued neural network according to a given task;
[0101] The training module is used to adjust the parameters in the complex-valued neural network by using the complex-valued second-order hybrid optimization algorithm to judge whether the construction termination condition is satisfied, if not satisfied, enter the verification update module, and if satisfied, then enter the fine-tuning module;
[0102] The verification update module is used ...
