摘要:In this paper, an application of a novel chemical reaction optimization (CRO) algorithm for training higher order neural networks (HONNs), especially the Pi-Sigma Network (PSN) has been presented. In contrast to basic CRO algorithms, the proposed CRO algorithm used to train HONN possesses two modifications. The reactant size (population size) remains fixed throughout all the iteration, which makes it easier to implement; and adaptive chemical reactions followed by a strictly greedy reversible reaction have been used which assist to reach the global minima in less number of iterations. The performance of 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 results from the following algorithms: basic CRO algorithm and the two most popular variants of differential evolution algorithm (DE/rand/1/bin and DE/best/1/bin). It is observed that the application of the proposed CRO algorithm to HONN training (CRO-HONNT) performs statistically better than that of other algorithms.
