The lab analyzes large-scale time-series data in real time to predict the future.
AboutAbout the lab
Transforming society through future prediction
The Intelligent Data Science Lab (Sakurai-Matsubara Lab) researches technologies that use large-scale data to analyze the temporal evolution of natural and social phenomena in real time and optimize social activities.
The lab develops technologies that find important patterns in large-scale time-series data obtained from sources such as IoT devices and predict future events.
The lab conducts joint research with many companies and also focuses on transferring the technologies it develops to industry.
The lab belongs to the Institute of Scientific and Industrial Research (SANKEN) at the University of Osaka, and accepts students as a cooperating chair of the Graduate School of Information Science and Technology.
Key terms
- Time-series data
- Data recorded in sequence along the flow of time. Sensor measurements are one example.
- IoT
- A mechanism that connects various devices to a network and collects data from them.
- Cooperating chair (kyoryoku koza)
- A framework in which a lab belonging to a research institute accepts students as a graduate school chair.

ResearchResearch themes
The lab aims to develop technologies that analyze natural and social phenomena that change over time, using large-scale data in real time, and optimize social activities. The lab keeps asking "what makes a technology truly practical?" and also works on introducing its technologies into society.
*Illustrative imageReal-time future prediction technology
For large-scale time-series data from sources such as IoT devices, the lab analyzes and learns how phenomena change over time using nonlinear dynamical models. It develops technologies that discover important patterns and predict future events with high accuracy and speed.
*Illustrative imagePrediction technology that runs on small devices
The lab develops lightweight, fast, and memory-efficient prediction technologies that run on small devices and embedded systems without requiring a PC. It is extending this work to the use of sensor data in manufacturing and to data analysis in healthcare.
