I am a Data scientist at Rakuten Inc., where I build machine learning models for Geospatial data. The applications that I am building include: human mobility analysis from spatio-temporal trajectories (GPS data) and ETA (Estimated Arriving Time) prediction for the intelligent logistics project; human spatial behavior analysis and customer profiling for online marketing.
I completed my Ph.D in Recommender Systems and Deep Learning at the National Institute of Informatics (NII), Japan. Previously, I received my master in Text mining at the Japan Advanced Instutute of Science and Technology (JAIST), Japan, and my bachelor degree in Computer science at the Hanoi University of Science and Technology (HUST), Vietnam.
Research interests: Deep Learning, Natural Language Processing, Recommender Systems.
