Random forest model training method and model training control system

Abstract

The invention relates to a random forest model training method and a model training control system. The random forest model training method comprises the following steps of: analyzing whether a modeltraining condition is satisfied or not by the model training control system; if the model training condition is satisfied, determining whether to carry out reconstruction training on a random forest model or not; if reconstruction training needs to be carried out on the random forest model, carrying out reconstruction training on the random forest model by utilizing sample data; and reconstructiontraining does not need to be carried out on the random forest model, carrying out correction training on the random forest model by utilizing the sample data. According to the method and the system provided by the invention, the random forest model training frequency can be decreased, the system burden can be lightened and the system efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of machine learning, in particular to a random forest model training method and a model training control system. Background technique [0002] In machine learning, random forest is a classifier that uses multiple trees to train and predict sample data. It is a classifier that includes multiple decision trees. Decision tree is the process of classifying data through a series of rules. At present, more and more companies that provide online services (for example, remote insurance, remote claim settlement, online financial management, etc.) use random forests to classify and identify users in their business systems, and then make accurate business recommendations for users based on the identification results. and handle. [0003] However, when there is new data available as sample data for iterative training to improve the accuracy of model recognition, the existing technical solution is to use both old sample...

Problems solved by technology

This kind of training scheme usually performs a reconstructive training once there is new sample data, and the number of training times is large, especially when the data of online business changes frequently, the training is too frequent and the system is overloaded, which affects the online business system Efficiency and effective development of online business
