Abstract

The present application provides a method and device for updating a model. The method for updating the model includes: when new repayment data is obtained, obtaining a training sample set to be updated and a model trained according to the training sample set; the training sample set includes repayment information of multiple customers, and Customer evaluation value of each customer; update the training sample set according to the repayment data to obtain an updated training sample set; train the model based on the updated training sample set to obtain an updated model . The method of this model update improves the accuracy and applicability of the model.

Description

technical field [0001] The present application relates to the field of computers, and in particular, to a method and apparatus for updating a model. Background technique [0002] With the development of financial technology, more and more financial institutions have introduced machine learning methods to establish credit scoring models to gradually replace manual approval methods, in order to reduce labor costs, improve work efficiency, and eliminate human instability. [0003] However, the conventional method of training a model is to use the historical data set as a sample to train the model, and the obtained model cannot adapt to the continuous changes of the data, so the accuracy and applicability of the model are low. SUMMARY OF THE INVENTION [0004] The purpose of the embodiments of the present application is to provide a method and apparatus for updating a model, so as to improve the accuracy and applicability of the model. [0005] In a first aspect, an embodimen...
