Abstract

Nowadays, with rapid growth in learning material and available internet access have made it easy to gain knowledge from online. But, the biggest challenge in e-learning education is how to teach learners effectively. Recommender systems are the most common information filtering systems in several domains to suggest relevant items to users. In the context of an e-learning platform, recommender system is an agent that suggests learners with learning courses based on their interests and previous behavior. The solution to effective teaching problem is preference elicitation that suggests learners based on their desired characteristics. The main objective of this research is to build an accurate recommender system model using a unique deep learning approach, Restricted Boltzmann Machines (RBM) and then compare with successful Matrix Factorization techniques. Our experiment proved that RBM outperformed Singular Value Decomposition (SVD) by 1.6% and Probabilistic Matrix Factorization (PMF) by 5.7%. These results will help data scientists to apply deep learning approach to e-learning recommender platforms.
