Manal Loukili, Fayçal Messaoudi · Statistics Optimization & Information Computing · 2024
This research introduces a novel methodology to enhance recommendation systems, specifically targeting the challenging cold-start problem. By creatively combining Collaborative Singular Value Decomposition (Co-SVD) with an innovative sparsity reduction approach, our study significantly improves recommendation accuracy and mitigates the challenges posed by sparse user-item interaction matrices. We conduct a comprehensive set of experiments, leveraging a sample e-commerce dataset, to demonstrate the efficacy of our approach. The results illustrate the superiority of our Enhanced Co-SVD model over traditional Co-SVD, content-based filtering, and random recommendation in various evaluation metrics. In particular, our methodology excels in cold-start scenarios, providing accurate recommendations for users with limited interaction history. The implications of our research extend to practical applications in e-marketing, user engagement, and personalized marketing strategies, highlighting the potential for enhanced customer satisfaction and business success. This work represents a critical step forward in the evolution of recommendation systems and underscores the importance of addressing the cold-start problem in modern online services.
