Optimized tourist point-of-interest recommendation through ARIMA and SVD in edge environment

In edge computing environments, accurate and timely Point of Interest (POI) recommendation is critical for enhancing tourist user experience and service efficiency. The distinct characteristics of edge computing, such as the mobility of users and the dynamic nature of spatial data, pose challenges to traditional tourist recommendation systems. This paper addresses these challenges by treating historical interaction data at various locations and time slots as a temporal sequence of POI matrices. We innovate by integrating Autoregressive Integrated Moving Average (ARIMA) and Singular Value Decomposition (SVD). This integration allows for the effective compression of large-scale spatial-temporal data while enabling the ARIMA model to predict POI preferences simultaneously and accurately. Experimental results demonstrate that our proposed approach significantly outperforms existing state-of-the-art methods in both prediction robustness and efficiency while guaranteeing prediction accuracy even in the sparse data environment. This improvement supports more robust and scalable POI recommendations, facilitating better decision making in mobile and dynamic user environments.
