Introduction

Welcome to Shimosaka Research Group.

This laboratory pursues innovative machine intelligence in ubiquitous and pervasive computing.

Research topics include deployments of wearable or ambient sensors for pervasive sensing, intelligent data analytics for modeling human behavior, and lifelog (quantify-self-technology).

The lab. is led by Masamichi Shimosaka who collaborate with graduate students in Dept of Computer Science in ISE/TITECH.

Towards succeeds on next level applications in ubiquitous computing, we collaborate with companies and governmental organizations as well as national scientific foundation in Japan.

Masamichi Shimosaka has moved to CS/ISE/TITECH from IMI/IST/UTokyo since July 2015. The group has restarted as lab. at TITECH!
