基于训练集的拟合优度r=10 ，模型的拟合结果非常好。根据表4，指数型

Based on the goodness of fit of the training set r=10, the model fits very well. According to Table 4, the exponents b and d of the exponential and power function information release methods are both less than zero, indicating that the information rate of the movie shows a monotonous decreasing trend over time. The coefficients a and s indicate the magnitude of the decrease.

The goodness of fit based on the training set is r = 10, and the fitting result of the model is very good. According to table 4, the exponents B and D of the exponential and power function information release modes are both less than zero, which indicates that the information rate of films presents a monotonous decreasing trend over time. The coefficients a and s indicate the extent of the decline.
