Research On Learning Resource Sequencing For E-learning Based On NCS Algorithm

Online learning is the hot spot in the field of educational technology research.Online learning has subverted the traditional way of education and learning,and personalized online learning has gradually attracted the attention of scholars at home and abroad.However,the recommendation of the individual learning resources still lack the effective mechanism,that is,the lack of the evaluation attribute of the learning resources is set.In this paper,the online learning resources are regarded as a constrained optimization problem,negative correlation algorithm is applied in learning resource sequencing.the mechanism of learning resources sequencing based on negative correlation is put forward.This paper analyzes the dilemma of learners using online learning platform,and points out the necessity of online learning resource sequencing.Based on the analysis of the literature resources at home and abroad,this paper expounds the connotation of learning resources,combs the collaborative filtering algorithm and the evolutionary algorithm in the study of learning resources,explores the learners' characteristics and the learning resource characteristic parameters.Besides that,the model of curriculum resource allocation is constructed,and the negative correlation algorithm is improved on the basis of this,and the learning resources are generated.The innovations of this paper mainly include,firstly,the characteristics of online learners are analyzed and the learners' attitude parameters are added to the learner and the learning resource characteristics,which enriches the parameters of the online learning model and conducive to the expression of the learning resource evaluation data.,secondly,Gray code encoding mechanism is introduced into the negative correlation algorithm,the improved algorithm to adapt to the requirements of learning resource characteristics.Thirdly,the improved algorithm is applied to the learning resource sequencing and the mechanism of learning resources sequencing based on negative correlation is put forward.
