Seeking a Postdoctoral Researcher (W20203)


Cognitive Behavioral Assistive Technology Team
Goal-Oriented Technology Research Group
RIKEN Center for Advanced Intelligence Project
(Laboratory head: Mihoko Otake)

Research field

The Center for Advanced Intelligence Project has been launched with subsidy from Ministry of Education, Culture, Sports, Science and Technology-Japan for “Advanced Integrated Intelligence Platform Project (AIP) -Artificial Intelligence/ Big Data/ Internet of Things/ Cybersecurity-”.
The Center conducts fundamental theoretical research and develops an innovative technology, with aiming to advance science and contribute to society or humanity.

This Center is a project with a maximum of 10 years from FY 2016.
AI nurturing or complementing intelligence of human are becoming much more important than ever before. Cognitive Behavioral Assistive Technology (CB-AT) Team puts emphasis on developing CB-AT which promotes cognitive reserve for prevention of cognitive decline and dementia of older adults which damage the intelligence of human necessary for social life. We develop conversational assistive AI based on Coimagination method, implement the AI to cognitive behavioral assistive systems, and evaluate the effects on human cognition and mind. Coimagination method is an image-based conversational assistive technology designed for utilizing cognitive functions which decline at mild cognitive impairment. In this context, machine learning methods applicable to the analysis of brainwave for estimating cognitive levels of older adults have been developed aiming for novel dementia digital biomarkers.
