Abstract

The present application proposes a model training data screening method, device, electronic equipment and storage medium. The specific implementation plan is: obtain multiple bad case data generated by the business model; use the classification model to classify the multiple bad case data, and obtain the classification categories to which the multiple bad case data belong; according to the classification category, use the classification model to classify The business data processed by the business model is screened to obtain the first training data of the business model. In the embodiment of the present application, on the basis of classifying the bad case data, the online business data is efficiently filtered according to the different performance effects of the business model on different types of data, and more valuable training data is recommended for the business model, which can achieve the following The purpose of maximizing the accuracy of the business model with the least amount of data.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a model training data screening method, device, equipment and storage medium. Background technique [0002] Bad Case (bad case) refers to the sample that cannot give accurate results when performing algorithmic model recognition and prediction. In the process of algorithm model training, a large number of rich and diverse samples such as Bad Case can be trained, so that the sample space can be greatly improved, and the trained algorithm model can be more generalized and robust. Therefore, the Bad Case generated by the algorithm model is more valuable for model training. How to find Bad Cases from the sample data set has become a key issue. However, under normal circumstances, there are too many return data of the business system in the existing environment, and it is difficult to find out which data is more valuable for model training.
