Abstract

The present application discloses a method and device for processing sample data, which relate to the technical field of data processing. The method of the present application includes: acquiring a sample data set, where the sample data set includes a plurality of unlabeled sample data; respectively inputting each unlabeled sample data into a preset scoring model to obtain a scoring result corresponding to each unlabeled sample data ; carry out multiple rounds of labeling processing on a plurality of unlabeled sample data according to the scoring result corresponding to each unlabeled sample data to obtain a plurality of first positive sample data and a plurality of first negative sample data; according to a plurality of first positive sample data The sample data and multiple first negative sample data perform multiple rounds of iterative training on the preset machine learning model and the preset deep learning model to obtain the first label prediction model and the second label prediction model; The two-label prediction model performs multiple rounds of labeling processing on multiple remaining unlabeled sample data.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a method and device for processing sample data. Background technique [0002] With the continuous development of society and the gradual upgrading of people's consumption concept, more and more people use loans to improve their living standards. In the process of loan applicants applying for loan services to the financial institution platform, in order to reduce the loan risk, the financial institution platform determines whether the lender will default on repayment according to the lender's personal information data and behavioral performance data, that is, to determine the lender Whether it is an inferior customer. [0003] At present, financial institution platforms usually first train a predictive model based on a large amount of labeled (high-quality customer label or poor-quality customer label) sample data (personal information data and / or behaviora...
