Abstract

The invention discloses an information vector determination method, device and equipment and a storage medium. The method comprises the steps: acquiring the features of a positive sample user and features of a negative sample user from a database, wherein the positive sample user is a user accessing new information in the database, and the negative sample is a user not accessing the new information in the database; obtaining a feature vector of the positive sample user and a feature vector of the negative sample user according to the features of the positive sample user and the features of thenegative sample user; constructing a first loss function according to the feature vector of the positive sample user, the feature vector of the negative sample user and the vector of the new information, processing the first loss function to obtain a minimized first loss function, and determining the vector of the new information according to the minimized first loss function. Therefore, the vector of the new information can be comprehensively determined by combining the characteristics of the positive sample user and the characteristics of the negative sample user in the website, and the accuracy of obtaining the vector of the new information is improved.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular, to a method, device, device, and storage medium for determining an information vector. Background technique [0002] In the field of information recommendation, the model is usually used to convert the characteristics of users and various types of information on the network into vectors, and by calculating the similarity between user vectors and information vectors, the degree of correlation between users and the information is measured, so that Highly relevant information is recommended to users. However, for new information on the Internet, since the model does not acquire the characteristics of the information, the vector of the information cannot be obtained. [0003] The solution in the prior art is usually to distribute new information on the network to some users, take the average value of the vectors of the users who click on the information, and us...
