My M.C work focused on sparse coding techniques and time series analysis for Brain Computer Interface. After finishing my M.C, I started working at Learning and Intelligent Systems Research Group of NTT CS Labs. I joined Ueda Research Laboratory of NTT CS Labs on April 2016. My current research interests are matrix and tensor factorization techniques and spatio-temporal data analysis.


We will organize a international workshop in conjunction with IEEE Bigdata 2017. (29 Nov. 2017)
The 3rd International Workshop on Smart Cities: People, Technology, and Data

New papers were accepted by IAAI, ICDM, ECMLPKDD 2017. (29 Nov. 2017)
