Abstract

The invention provides a model updating method and device. The model updating method comprises the steps of when the new repayment data is acquired, obtaining a training sample set to be updated and amodel obtained through training according to the training sample set, wherein the training sample set comprises the repayment information of a plurality of clients and a client evaluation value of each client; updating the training sample set according to the repayment data to obtain an updated training sample set; and training the model based on the updated training sample set to obtain an updated model. The model updating method improves the accuracy and applicability of the model.

Description

technical field [0001] The present application relates to the field of computers, in particular, to a method and device for updating models. 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 achieve the purpose of reducing labor costs, improving work efficiency, and eliminating artificial instability. [0003] However, the conventional method of training the model is to use the historical data set as a sample to train the model, and the obtained model cannot adapt to the continuous change of the data, so the accuracy and applicability of the model are low. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a method and device for updating a model, so as to improve the accuracy and applicability of the model. [0005] In the...
