As the digital world evolves, sequential recommendation systems are becoming crucial for enhancing user engagement by personalizing the digital experience. These systems analyze a user's interaction history and context, predicting future actions with high relevance. Utilizing deep learning techniques, such as Graph Neural Networks, these models handle complex user-item relationships effectively, especially when integrated with temporal data.

This research introduces Temporal Attention Graph-Optimized Networks, a robust architecture that incorporates temporal dynamics into graph-based models. By capturing the sequence and timing of interactions, the proposed model aims to provide more accurate predictions, significantly improving the performance of recommendation systems in various domains like e-commerce and social networking.
