Abstract

The application discloses a data screening method, device and computer-readable storage medium. First, perform primary feature selection on the acquired data to obtain a candidate feature set that can be used to build a model; then, use the candidate feature set and corresponding candidate feature data to build a model, and obtain a model evaluation index After that, based on the model evaluation index value and the candidate feature set, gradually delete the features in the candidate feature set that satisfy the model evaluation index value and the model evaluation index value of the first model less than the first change threshold, Until the target feature set that meets the constraints of computing resources or funding is obtained. In this way, the effect of the model can be taken into account when building the model, and the target feature set that meets the constraints of computer resources or funds can be obtained, thereby achieving a higher input-to-output ratio.

Description

technical field [0001] The present application relates to the field of information processing, and in particular to a data screening method, device and computer-readable storage medium. Background technique [0002] At present, when building some predictive models, in order to achieve a certain accuracy, we will try our best to obtain as much training data as possible, which will cause feature disaster. However, due to the limitation of computing resources or funds during modeling, it is necessary to further screen the features and their quantity to be used under the premise of ensuring that the model effect is not affected. Contents of the invention [0003] In order to solve the above technical problems, the applicant creatively provides a data screening method, device and computer-readable storage medium. [0004] According to the first aspect of the embodiments of the present application, a data screening method is provided, the method comprising: obtaining a first fe...
