The lab analyzes time-series data in real time to predict the future.
AboutAbout the lab
Changing society through predicting the future.
The Intelligent Data Science Lab (Sakurai-Matsubara Lab) researches technologies that use large-scale data to analyze the time evolution of natural and social phenomena in real time and optimize social activities.
The lab is developing an AI technology platform that provides information in real time for prediction, factor analysis, trouble prediction, and behavior optimization.
Focusing on time-series data such as IoT big data, the lab discovers important patterns and predicts future events.
The lab belongs to the Institute of Scientific and Industrial Research at Osaka University. As a cooperating chair of the Graduate School of Information Science and Technology, it accepts undergraduate students from the Department of Electronic Information Engineering as well as graduate students.
Key terms
- Time-series data
- Data recorded along the flow of time, such as sensor measurements and web click logs.
- IoT
- A mechanism in which sensors are attached to everyday devices so that data can be collected and the devices connected to each other.
- Cooperating chair (kyoryoku koza)
- An arrangement in which a lab belonging to a research institute also accepts students as a chair of a graduate school.
