Problems solved by technology

[0004] The invention provides a method and system for predicting click-through rate based on multi-level logistic regression. Through multi-level logistic regression, under the premise that the dimensions remain unchanged and the number of samples remains unchanged, the amount of calculation is reduced to solve the problem of current click-through rate prediction. The problem of large amount of data and inaccurate prediction

Abstract

The invention discloses a click rate predicting method and system based on multistage logistic regression. The method includes: analyzing obtained click rate data, analyzing factors affecting click rate, and selecting feature vectors in the factors to build feature models; using multistage logistic regression models to perform machine learning on the feature models to obtain prediction models; using the prediction models to predict the to-be-predicted click rate data. The method has the advantages that by multistage logistic regression, calculation amount can be reduced and calculation speed can be increased while dimensionality and sample number are unchanged, and the problem that the current click rate prediction is large in data amount and inaccurate in prediction.

Description

technical field [0001] The invention relates to the field of Internet big data machine learning processing, in particular to a method and system for predicting click rate based on multilevel logistic regression. Background technique [0002] With the improvement of global informatization, Internet applications are becoming more and more popular. Compared with traditional media advertisements, Internet advertisements account for an increasing proportion. In recent years, with the rise of online games and e-commerce and the development of online alliances that emphasize long-tail traffic, advertisers have attracted more and more attention to the actual effect of online advertising. By statistically calculating the click-through rate of advertising links, we can understand the advertisements that different users are interested in, so as to display the corresponding advertisements to each user more accurately, so as to increase the click-through rate of advertisements, improve t...
