Problems solved by technology

[0003] However, the above method cannot reflect the non-linear correlation between the various CTR prediction models, and when the magnitudes of the CTR prediction models are inconsistent, the effect of simply linearly adding the scores will become poor, resulting in the estimation of the CTR of the candidate resources. Accuracy drops

Abstract

The invention discloses a resource sequencing method and device. The resource sequencing method comprises the following steps: acquiring candidate resources; calculating first click through rate (CTR) scores of the candidate resources based on a logistic regression (LR) model; calculating second CTR scores and uncertainty scores of the candidate resources based on a linear confidence upper limit LinearUCB model; inputting the first CTR scores, the second CTR scores and the uncertainty scores serving as input features into a gradient boosting decision tree (GBDT) model, and calculating pre-estimated scores of the candidate resources based on the GBDT model; and sequencing the candidate resources according to the pre-estimated scores. Through adoption of the resource sequencing method, the accuracy of CTR pre-estimation can be increased effectively, so that sequencing optimization of the candidate resources is realized; candidate resources more preferred by a user are presented preferentially; and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for sorting resources. Background technique [0002] In fields such as Internet search engines, product or advertisement promotion, it is often encountered that there are many candidate resources, but only a limited number of candidate resources can be displayed each time. In order to give priority to displaying candidate resources that are most interesting to users, machine learning is mainly used to estimate the CTR (ClickThroughRate, click-through rate) of candidate resources at present, and the candidate resources are sorted according to CTR. For example, to calculate the CTR of a certain candidate resource, it is mainly to linearly add the scores of multiple CTR prediction models. [0003] However, the above method cannot reflect the non-linear correlation between the various CTR prediction models, and when the magnitudes of the CTR predicti...
