Abstract

The invention relates to the field of artificial intelligence, and provides a course recommendation method and device based on transfer learning, equipment and a medium, which can perform preprocessing for the problem of high sparsity of a matrix, facilitate calculation, and ensure the availability of data in a similarity calculation process. The method includes: obtaining behavior data generatedby similar users in the target domain to construct a target matrix, performing analysis according to the target matrix to obtain a preference prediction value of the target user for each course in thesource domain, determining the target course according to the preference prediction value of each course, and pushing the target course; and achieving automatic and accurate recommendation of coursesin combination with transfer learning and an improved similarity algorithm. The invention also relates to a blockchain technology, and the target course can be stored in the blockchain.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a transfer learning-based course recommendation method, device, equipment and medium. Background technique [0002] One of the important goals of smart training is to achieve differentiated training course recommendations according to the individual needs of agents, which can be achieved by designing an excellent recommendation system model. The recommendation model often needs to use a large amount of user historical behavior data as input, and at the same time use other auxiliary information to predict the user's preference for a certain course, so as to achieve accurate push of training courses. At present, according to the seniority and rank of the agents, the full number of agents are divided into five groups: new recruits within one year, excellent talents within one year, general talents over one year, excellent performers over one year, and supervi...
