Abstract

The invention discloses a data evaluation and model training method and device, equipment and a storage medium, relates to the technical field of communication, and aims to solve the problem that a data evaluation result is inaccurate. The method comprises the following steps: obtaining a candidate data set of a corresponding sample as a training sample according to a first sample and a second sample, wherein the number of variables included in the training sample is greater than 1; selecting candidate variables from the variables of the training sample; determining a model algorithm; and inputting the data set corresponding to the candidate variable into the model algorithm, and training to obtain the data evaluation model. According to the embodiment of the invention, the accuracy of theobtained evaluation result can be improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data evaluation and model training method, device, equipment and storage medium. Background technique [0002] With the development of financial business, it is more and more urgent to control the personal credit of users. At present, relying on credit information data alone is not enough to cover all the population. Therefore, on the basis of existing credit information data, it is necessary to rely on data services provided by other companies to evaluate users' personal credit more comprehensively and improve the existing credit information system. [0003] Before a new data source is connected, it is necessary to reasonably evaluate the effect of the data source. Most of the current evaluation schemes only consider the evaluation effect of the data source from the perspective of univariate or model, which leads to inaccurate evaluation results of the data. ...
