Abstract: Elman neural network is a classical kind of recurrent neural network.Adaptive Quantum-Behaved Particle Swarm Optimization (AQPSO) algorithm is proposed in this paper in order to improve network’s performance.By applying AQPSO algorithm to train the net parameters adopted in the Elman neural network,the generalization ability of the Elman neural network is improved.Experimental results with Zhongji stock data sets show that obtained network model has not only good generalization properties,but also has better stability.It illustrates that Elman net with AQPSO optimization algorithm has the promising application in stock data forecasting.
