| 中文摘要:针对传统的境外旅游人数预测模型预测误差大的情况,设计了一种RBF神经网络的境外旅游人数预测模型。首先对旅游样本数据进行归一化处理,对境外旅游人数变动统计,然后通过预测种群构建、评估适应值、惩罚项设置、预测序列平稳性检验、模型预测五个过程完成了基于RBF神经网络的境外旅游人数预测模型的设计。最后,通过实验证明,本文的RBF神经网络的境外旅游人数预测模型比传统的境外旅游人数预测模型误差小,能够准确对境外旅游人数预测。 |

| Abstract:in view of the large prediction error of the traditional prediction model of the number of overseas tourists, a RBF neural network prediction model of the number of overseas tourists is designed. Firstly, the tourism sample data is normalized, and the number of overseas tourists is counted. Then, the prediction model of overseas tourists based on RBF neural network is designed through five processes: prediction population construction, evaluation of fitness value, penalty item setting, prediction sequence stability test and model prediction. Finally, experiments show that the RBF neural network model designed in this paper has less error than the traditional model, and can accurately predict the number of overseas tourists. |
