Research Summary

Analysis of the dynamic changes in people’s flow and detection of people’s behaviors are becoming more and more important in recent society. By analyzing and predicting a large amount of information on IoT sensing and social media, interactive and dynamic behavior and information navigation tailored to users are going to be realized and enhanced by applying deep learning in tourism. Specifically, we are researching time-series data analysis and clustering, multilingual spoken language processing, dynamic navigation, and route optimization.
