Abstract

The invention relates to a data estimation method and device. The method comprises steps of obtaining user historical behavior data and historical user portrait data in a first historical time period,and determining first preprocessing data; obtaining user target behavior data in a second historical time period; based on the historical user portrait data, decentralizing the first sub-behavior data, the second sub-behavior data, the target behavior data and the first preprocessing data to obtain third sub-behavior data, fourth sub-behavior data, target behavior processing data and second preprocessing data; regressing the second preprocessed data and the third sub-behavior data to obtain a third sub-behavior data estimated value; performing regression on the third sub-behavior data estimated value, the fourth sub-behavior data and the target behavior processing data to obtain estimated parameters; and obtaining current behavior data and current user portrait data of the user at the current moment, and estimating future behavior data of the user based on the estimation parameters. The method is advantaged in that an endogeny problem can be solved, and the future behavior data of theuser can be accurately estimated.

Description

technical field [0001] The present disclosure relates to the technical field of computer processing, in particular to a data estimation method and device. Background technique [0002] At present, many business scenarios need to analyze user behavior data. For example, in the video field such as short video and live broadcast, it is possible to analyze and solve practical problems by obtaining massive user behavior data. As a common analysis model, regression model is often used to study factors The relationship between variables and independent variables. Regression can help explore the correlation between variables and obtain quantitative analysis results. For example, as live broadcast e-commerce gradually enters everyone's life, in order to analyze the impact of users' purchase behavior in e-commerce live broadcast rooms on their future reward behavior Influence, usually the user's purchase amount in the live broadcast room is used as the independent variable, and the u...
