Traditional recommender systems struggle to adapt to users’ changing preferences due to their reliance on single-task learning. This research proposes a multi-task learning (MTL) approach that jointly addresses personalized rating prediction, contextual tag recommendation, and temporal preference modeling. By using shared embeddings and task-specific branches, the model better captures dynamic user behavior and context, improving recommendation accuracy and relevance.
