After analyzing and comparing various forecasting methods, it was found that the forecast results obtained using the Holt-Winters Additive model are superior to other methods in terms of accuracy (such as MAPE), especially when dealing with relatively stable seasonal fluctuations. Therefore, the Additive model is tentatively selected as the preferred solution for current sales forecasting.
At the same time, in order to better automate the data analysis and forecasting process, I began to learn basic Python programming, especially basic operations related to data processing. At this stage, I have mastered how to use the polars library for file reading, such as importing sales data from local through read_csv() or read_excel() statements.
