Problems solved by technology

Although these methods have alleviated the cold start problem of users to a certain extent, they are relatively subjective and one-sided, and require specific domain knowledge and more user interaction, resulting in poor course recommendation effect for cold start users, and cannot be accurate. Make course recommendations

Abstract

The invention relates to the technical field of artificial intelligence, and provides a course recommendation method and device based on artificial intelligence, an electronic device and a medium. The method comprises the following steps of generating a user information matrix in an information field and a user course matrix in a course field, then calculating the similarity between any two users in the information field through the user information matrix, and constructing a first user field set according to the similarity so as to construct a second user field set of the course field according to the user course matrix and the first user field set; migrating the information reading preference behavior of the user to the course learning preference behavior in the course field by using the migration learning thought, and finally carrying out mutual course recommendation for the two similar second users in the second user field set, so that the cold start problem in a course recommendation model is effectively solved, the courses can be recommended to multiple users in a personalized manner at a time, and the mutual recommendation of the courses of the two similar users is achieved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based course recommendation method, device, electronic equipment and medium. Background technique [0002] The course recommendation model usually uses a large amount of user historical behavior data as input, and at the same time uses other auxiliary information to predict the user's preference for a certain course, so as to achieve accurate push of differentiated training courses. However, the course recommendation model often faces the problem of user cold start, that is, when there is a lack of historical interaction data between users and courses, the course recommendation model cannot judge the user's demand preference for courses, and thus cannot implement targeted course recommendations. [0003] The inventor found in the process of implementing the present invention that most of the existing methods for solving the user ...
