布谷鸟搜索(CS)算法是一种新型的基于仿生学原理的元启发式算法,具有很好的全局优化能力,但其存在后期收敛速度慢、计算精度不高等不足。通过将交叉熵(CE)方法嵌入到CS中构建一种改进的CS算法,基准测试函数集的测试结果表明改进算法收敛速度和计算精度都有了明显提高。用改进的算法实现对人工神经网络的训练,实验结果显示新算法训练的神经网络收敛速度更快,能有效避开局部极小。最后用所建立的人工神经网络对中国人口总量进行了预测。

Cuckoo search is a novel meta-heuristic algorithm based on bionics. It has good ability to search for global optimum ,but suffers from slow searching speed in the last iterations and poor accuracy. The cross-entropy method is embedded into cuckoo search algorithm and an improved cuckoo search algorithm is introduced. The testing results of benchmark functions show the improved algorithm obtains good performance of convergence speed and high accuracy. The proposed algorithm is employed as a new training method for artificial neural network. , and the experimental results show that the proposed algorithm outperforms for training neural networks in terms of converging speed and avoiding local minima. Finally ,the artificial neural network with learning algorithm based on the improved algorithm is employed to forecast total population of China.
