Problems solved by technology

Although this assumption limits the scope of application of the Naive Bayesian model to a certain extent, in practical applications, this model not only greatly reduces the complexity of Bayesian network construction, but also in many cases that do not meet this assumption , Naive Bayes also shows considerable robustness and efficiency

Abstract

The invention discloses an e-commerce website cheat user identification method and system based on a random forest algorithm. The system comprises an e-commerce website user data processing module, an e-commerce website user data storage module, an e-commerce website user data analysis module and a result display module, wherein the e-commerce website user data processing module, the e-commerce website user data storage module, the e-commerce website user data analysis module and the result display module are connected in sequence. The method includes the steps of data collection, data pre-processing, data conversion, data analysis, data display and the like. On the basis of the random forest algorithm in a machine learning method, static data and dynamic data of a user are collected, data mining and data analysis are carried out fast, and not only are completeness, continuousness and effectiveness of information of the user guaranteed, but also a good classification result is obtained.

Description

technical field [0001] The invention belongs to the field of e-commerce, in particular to a method and system for identifying fraudulent users of an e-commerce website based on a random forest algorithm. Background technique [0002] With the rapid development of information technology and the expansion of the Internet, the concept of the traditional market has undergone tremendous changes in the scope of quantity: it is manifested in the expansion of the time dimension and the expansion of the space dimension. The market boundaries formed by differences in geography, politics, and concepts in traditional markets have become increasingly blurred, and the rapid development of the Internet has enabled high-level sharing of information, further weakening the obstacles for people to cross time and space. E-commerce was born under this background It has grown rapidly with the development of the Internet and has become increasingly mature after entering the 21st century. E-commer...
