Abstract
Online education growth requires the development of effective customized recommendation systems to improve student involvement and educational performance. This research, suggests new hybrid model based on Convolutional Neural Networks (CNNs) with graph analysis to improve online course recommendations by delivering more tailored suggestions to students. Our suggested process starts with extracting raw student and course data from a database which is preprocessed for training a CNN model. The purpose of this CNN model is to identify essential characteristics from student records and educational performance data and course information for predicting student course selection probabilities. The proposed model then defines the students as the fundamental entities of a graph network while behavioral and educational relationships create the edges between them. The application of graph analysis serves to detect behavioral patterns among students while predicting new possible relationships through solutions to cold start problems. This goal is achieved by applying the link prediction technique on the constructed graph. The generated course recommendations result from combining information derived from CNN models and graph analysis techniques. Experimental results based on 12,898 students from the Islamic Azad University E-Campus Tehran, Iran validated this hybrid approach through better performance than traditional methods which yielded precision at 0.8336 and F1-Score at 0.3347 thus confirming its ability to provide precise relevant course recommendations.
