摘要:In this paper, an application of an adaptive differential evolution (DE) algorithm for training higher order neural networks (HONNs), especially the Pi-Sigma Network (PSN) has been introduced. The proposed algorithm is a variant of DE/rand/2/bin and possesses two modifications to avoid the shortcomings of DE/rand/2/bin. The base vector for perturbation is the best vector out of the three randomly selected individuals for mutation, which actually assists intensification keeping the diversification property of DE/rand/2/bin; and novel mutation and crossover strategies are followed considering both exploration and exploitation. The performance of the proposed algorithm for HONN training is evaluated through a well-known neural network training benchmark i.e. to classify the parity-p problems. The results obtained from the proposed algorithm to train HONN have been compared with solutions from the following algorithms: the basic CRO algorithm, CRO-HONNT and the two most popular variants of the differential evolution algorithm (DE/Rand/1/bin and DE/best/1/bin). It is observed that the application of the proposed algorithm to HONN training (DE-HONNT) performs statistically better than that of other algorithms.
