Abstract Multi-Criteria Recommender Systems (MCRSs) improve personalization by incorporating multiple user preferences.However, their application in Technology-Enhanced Learning (TEL) remains limited due to challenges such as data sparsity, over-specialization, and cold-start problems.Traditional techniques, such as Singular Value Decomposition (SVD) and SVD + + , struggle to effectively model the complex interactions within multi-criteria rating data, leading to suboptimal recommendations.This paper introduces a hybrid DeepFM-SVD + + model, which integrates deep learning and factorization-based techniques to improve here multi-criteria recommendations.
The model captures both low-order feature interactions using factorization machines and high-order dependencies through deep neural networks, enabling more adaptive recommendations.To evaluate its performance, the model is tested on two multi-criteria datasets: ITM-Rec (TEL domain) and Yahoo Movies (non-TEL domain).The experimental results show that DeepFM-SVD + + consistently outperforms the traditional My Mom Dad Is Well Trained Funny Cartoon Dog Gift For Dog Lover Personalized Shirt techniques across multiple evaluation metrics.The findings highlight significant improvements in accuracy, demonstrating the model’s effectiveness in sparse datasets and its generalization across domains.
By addressing the limitations of existing MCRS techniques, this study contributes to advancing personalized learning recommendations in TEL and expands the applicability of deep learning-based MCRS beyond educational contexts.
