Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0028] The technical solutions provided in the embodiments of the present application are applicable to multi-target fusion evaluation in various scenarios.

[0029] Taking the field of live broadcasting as an example, suppose the fusion score of the target anchor is calculated. The fusion score is determined by fusing the scores of the target anchor in multiple dimensions to reflect the comprehensive ranking of the target anchor. For example, the above-mentioned multiple dimensions may include multiple different dimensions such as watching, following, and tipping, and the score of a certain dimension is used to represent the probability of the user performing the behavior of this dimension on the target anchor. Based on the scor...

Abstract

The invention discloses a weight determination method and device for multi-target fusion evaluation, equipment and a storage medium, and relates to the technical field of computers and the Internet. The method comprises the following steps: obtaining scores of an offline sample in n dimensions based on multi-target prediction, wherein n is an integer greater than 1; normalizing the scores of the ndimensions to obtain normalized scores of the n dimensions wherein the normalization scores of the n dimensions belong to the same order of magnitude; determining weight values respectively corresponding to the n dimensions based on the normalized scores of the n dimensions and the label information of the offline sample in the n dimensions, wherein the weight value is used for carrying out fusion processing on the scores of the n dimensions to obtain a fusion score. According to the embodiment of the invention, the method can improve the accuracy of the determined weight value correspondingto each dimension in a multi-target fusion evaluation scene.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computers and the Internet, and in particular to a weight determination method, device, device and storage medium for multi-objective fusion evaluation. Background technique [0002] Multi-target fusion evaluation refers to scoring the target object from multiple dimensions, and combining the weight values ​​corresponding to each dimension to determine the fusion score of the target object. [0003] For example, in the live broadcast field, the ranking model not only needs to predict whether the user will watch the candidate anchor, but also predict whether the user will pay attention to the candidate anchor, and predict whether the user will reward the candidate anchor, so a ranking model will output multiple dimensions The scores of , respectively represent the probability of users watching, following, and rewarding candidate anchors. Then, based on the scores of the multipl...
