Enhancing App Usage Prediction Accuracy with GCN-Transformer Model and Meta-path Context

In this paper, we introduce MP-GT, a novel Graph Neural Network model that leverages meta-path-guided optimization within the GCN-Transformer framework to enhance application (App) usage prediction.Our approach addresses issues such as suspended animation and over-smoothing by extracting both local subgraph structures and global graph structures using the GT method.Furthermore, we enhance the capture of semantic information and App usage patterns by incorporating a meta path-guided objective function.Extensive experiments demonstrate that MP-GT outperforms the widely adopted semantic-aware representation learning via Graph Convolutional Network (SA-GCN) by 13.33% and surpasses the popular context-aware App usage prediction with heterogeneous graph embedding (CAP) by 74.02% in terms of Accuracy@1.Moreover, MP-GT reduces training time by 79.47% compared to SA-GCN.These findings validate that our approach not only achieves higher prediction accuracy but also converges faster than the baseline models.Therefore, MP-GT proves to be an effective and superior solution for the app usage prediction task.
