| 摘 要： | 以广州车牌竞拍价格数据集为数据来源, 采用线性回归并结合k折交叉验证, 研究小样本数据集的预测方法。为解决小样本局部特异性数据导致的验证误差增大的问题, 提出验证之前先对数据进行全局混洗的策略。最后通过实验验证了此策略可以明显降低验证误差, 以此为基础, 通过多组实验验证, 确定了合适的参数, 结果表明最终预测值的总平均正确率达到了95%。

| Abstract: | Based on the Guangzhou license plate auction price data set, linear regression combined with k-fold cross-validation is used to study the prediction method of a small sample data set. In order to solve the problem of increased verification errors caused by local specific data in a small sample set, a strategy to shuffle the data globally before verification is proposed. Finally, it is verified through experiments that this strategy can significantly reduce the verification error. Based on this, through multiple sets of experimental verification, the appropriate parameters are determined, and the results show that the total average correct rate of the final predicted value has reached 95%. |
