Description
Summary:Recommendation systems are becoming essential components of contemporary online goods and services, and they significantly affect customer satisfaction. Recommendation systems are designed to empower customers in their decision-making process by providing personalized recommendations. Meta-learning has proven to be effective in addressing user cold-start problems in recommendation systems. Many meta-learning-based recommendation systems designed for the cold-start problem are gradient-based. The existing frameworks require optimization techniques to maximize the potential of hyper networks, enabling them to adapt and generate compatible parameters for efficient learning as meta-learners. However, these frameworks often lack contextual knowledge from users to provide suitable initial guidelines in the recommendation network for new users. We propose a meta-learning-based framework that improves cold-start recommendation accuracy by incorporating user behavior and preferences. Evaluations on MovieLens 100K and DBook datasets show our IMETA-GNN model outperforms state-of-the-art baselines, achieving accuracies of 82% and 75%, respectively. Performance evaluation demonstrates that our proposed method outperforms several state-of-the-art metalearning recommendation systems in addressing the user cold-start conundrum.
