I’m a Ph.D. student at Sakurai&Matsubara Lab., Osaka University.
I’m also working as a project researcher at SANKEN (The Institute of Scientific and Industrial Research at Osaka Univ.).
My research focuses on machine learning and data mining for time series data (particularly time series forecasting and anomaly detection), and tensor data mining (tensor decomposition and scalable algorithms for tensor data streams).
