Embodiment 1

[0057] The present invention provides a personalized learning path optimization method based on the improved particle swarm optimization algorithm, and its optimization method is as follows:

[0058] Step 1: Establish a mathematical model of the learning path optimization problem

[0059] In an online learning system, in order to be able to recommend personalized learning resources and paths to learners, on the one hand, it is necessary to consider the knowledge mastery and learning costs of the learners themselves, and on the other hand, it is necessary to consider the learning sequence of the target knowledge points. existing literature [5,8,9] Among them, when scholars established the mathematical model of the learning path optimization problem, they took into account factors such as concept relevance, learning difficulty, and learner knowledge level, but did not take the order relationship into the mathematical model as an essential constraint relationship. To a certain ex...

Description

technical field [0001] The present invention relates to the technical field of particle swarm optimization algorithm, and more specifically relates to a personalized learning path optimization method based on improved particle swarm optimization algorithm. Background technique [0002] The online learning system is a knowledge service method that relies on emerging media such as the Internet to deliver learning content. Driven by information technology, online learning has gradually become a mainstream way of acquiring knowledge. Although the online learning system has accumulated a large number of learning resources, it is often difficult for learners to quickly find the appropriate learning path and learning content from the massive resources. Therefore, the intelligence and personalization of online learning systems have become a research hotspot for scholars at home and abroad. A key issue in the study of intelligent learning systems is the optimization of learning pat...
