The lab predicts the future through real-time analysis of time series data.
AboutAbout the lab
Transforming society through predicting the future.
The Sakurai-Matsubara Lab researches technology that uses large-scale data to analyze the time evolution of natural and social phenomena in real time and optimize social activities.
Targeting time series data such as IoT big data, the lab analyzes how various phenomena and activities change over time, working on discovering important patterns and predicting future events.
The lab conducts joint research with companies toward practical application and also works on transferring its technology to industry.
The lab belongs to the Institute of Scientific and Industrial Research at Osaka University and serves as a cooperating chair of the Graduate School of Information Science and Technology. Lab assignment is open to graduate students and third- and fourth-year undergraduates.
