Study on Budget Preparation and Forecast Model Based on Apriori Rule Algorithm

Association rule algorithm and data mining technology can discover the hidden rules of many target data information, apply relevant technologies to budget management, mine and process the historical budget information and financial revenue and expenditure information of previous years, and can discover some hidden relevant information to guide the budget management of enterprises. This paper introduces the basic concept and algorithm flow of association rules, analyzes the Apriori algorithm in detail, and optimizes the association rule mining algorithm after introducing concept level and dimension level. Based on the idea of Apriori algorithm to optimize the enterprise budget management process, and build budget analysis and forecast model, which can conduct regression analysis based on historical financial data and forecast the revenue budget of the next year, which is used to guide enterprise budgeting. The model analysis results show that the budget forecasting model in this paper has higher accuracy and reliability than the traditional forecasting methods.
