Object classification method and device, electronic equipment and storage medium

Abstract

The invention provides an object classification method and device, electronic equipment and a storage medium, and belongs to the technical field of big data. The method comprises the steps of obtaining feature data corresponding to an object; performing dimension reduction processing on the feature data by using an auto-encoder to obtain first processing data, and taking the first processing data as target data; the target data are input into a plurality of first classification models respectively, so that the plurality of first classification models output first prediction scores, and the plurality of first classification models are obtained by training target sample features obtained through dimensionality reduction processing based on the auto-encoder in advance; inputting the first prediction score into a second classification model to obtain a second prediction score, and inputting the first prediction score into the second classification model to obtain the second prediction score; and determining a target classification to which the object belongs based on the second prediction score. Therefore, the classification effect can be improved.

Description

technical field [0001] The present application relates to the technical field of big data, and in particular, to an object classification method, apparatus, electronic device and storage medium. Background technique [0002] At present, the commonly used classification methods mainly use relatively simple machine learning algorithms such as tree methods and logistic regression for modeling. In the modeling, the input variables are usually encoded and the predictive ability is evaluated according to the IV value (Information Value), or, according to the importance of the input variables, a small number of variables are selected from all variables for modeling. However, with this method of modeling, there is a lot of loss of variable information. Therefore, it is difficult to ensure the classification effect by using the current classification method to classify users. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide ...
