Abstract

The embodiment of the invention provides a data sorting method and device, and the method comprises the steps: selecting a first number of online business data from a plurality of online business data corresponding to a target feature category under each feature dimension, inputting the selected online business data into a sorting model, and obtaining a corresponding sorting result, and a second number of to-be-processed target business events are determined based on the sorting result, that is, online business data input to the sorting model are selected under the target feature category of each feature dimension, and the target accuracy rate corresponding to the target feature category meets a preset condition. The target accuracy rate can represent the quantity proportion of the positive samples which are predicted correctly in the first quantity, so that a certain quantity of online business data is selected under the target feature categories of the plurality of feature dimensions, and more positive samples can be selected; therefore, the number of positive and negative samples input into the second business data set of the sorting model is ensured to be more balanced, and the topN accuracy of the sorting model is improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a data sorting method and device. Background technique [0002] Currently, with the rapid development of machine learning technology, machine learning is widely used in many business scenarios. The service provider can train the machine learning model by collecting user data in the business scenario, so that the service provider can use the trained machine learning model to predict the user's behavior, thereby providing users with better services. [0003] Among them, for some specific business scenarios, such as complaint scenarios, the ranking model can be used to predict users who may complain, but due to limited human resources, only a certain number of user demands can be processed every day. Therefore, it is necessary to provide a method that can A technical solution for making the prediction results of the ranking model more accurate. Contents ...
