of higher-order polynomial curve, but this method of fitting can better obtain the development trend of data. In contrast to the over-fitting phenomenon of high-order polynomial curves, for low-order curves, there is no good description of the data, which leads to the case of less-fitting. So in order to better describe the characteristics of the data, using the 2-order curve to fit the data to avoid the occurrence of overfitting and under-fitting phenomenon.Training and testingWe trained to ge
