Application of Classification Regression Tree Algorithm in Accounting Information System

Classification regression tree algorithm is a machine learning method based on decision tree, and its application in Accounting information system has important value. Accounting information system refers to the system used to record, process and report financial transactions and business data. It has a wide range of applications, including financial reporting, risk management, investment analysis, etc. This paper introduces the application of classification regression tree algorithm in Accounting information system. Firstly, construct a training dataset by collecting and organizing relevant financial and business data. Then, the classification regression tree algorithm is used to analyze and model the training data to construct a model that can predict and classify financial information. Finally, the experiment shows that the classification effect of the Accounting information system will be significantly improved after the classification regression algorithm is used in the Accounting information system.
