针对高校毕业生失业数据的非线性、小样本、高维度特点,采用主成分分析和BP神经网络相结合的方法,构建了高校毕业生失业率预测模型,并借助河北省1995—2016年高校毕业生失业数据进行了实证研究.结果表明,该模型能有效地反映河北省高校毕业生失业率的变化趋势,预测精度高于仅用BP神经网络构建的预测模型.
A prediction model for the unemployment rate of college graduates was developed based on principal component analysis and BP neural network, followed by analyzing the unemployment data of college graduates in Hebei province in the years 1995—2016.The results show that the model can effectively reflect the variation tendency of the unemployment rate of college graduates in Hebei province and the prediction accuracy of the model is higher than that of the model only based on BP neural network.
