Title: Exploring Robotic Minds by Using the Frameworks of Predictive Coding and
Active Inference
Abstract : My research has investigated how cognitive agents acquire structural
representation via iterative interaction with their environments, exercising agency
and learning from resultant perceptual experience. Over the past two decades, my
group has tackled this problem by applying predictive coding and active inference
to development of cognitive constructs of robots. Under the principle of predictive
coding, intense interaction occurs between top-down intention, which acts
proactively on the outer world, and the resultant bottom-up perceptual reality
accompanied by prediction error. We have found that compositionality, which enables
some conceptualization, including senses of minimal self and narrative self, can
emerge via iterative interactions, as a result of downward causation in terms of
constraints such as multiple spatio-temporal scale properties applied to neural
network dynamics. Finally, I will introduce our recent results that may account for
how abnormal development leads to some developmental diseases, including autism
spectrum disorders (ASD) and schizophrenia, which may be caused by different types
of failures in the top-down bottom-up interaction.
Bio: Jun Tani received the B.S. degree in mechanical engineering from Waseda
University, Tokyo, Japan in 1981, dual M.S. degree in electrical engineering and
mechanical engineering from the University of Michigan, Ann Arbor, MI, USA in 1988,
and the D.Eng. degree from Sophia University, Tokyo in 1995. He started his
research career with Sony Laboratory, Tokyo, in 1990. He had been a Team Leader of
the Laboratory for Behavior and Dynamic Cognition, RIKEN Brain Science Institute,
Saitama, Japan, for 12 years until 2012. He was a Visiting Associate Professor with
the University of Tokyo, Tokyo, from 1997 to 2002. He was a Full Professor with the
Electrical Engineering Department, Korea Advanced Institute of Science and
Technology, Daejeon, South Korea, from 2012 to 2017. He is currently a Full
Professor with the Okinawa Institute of Science and Technology, Okinawa, Japan. His
current research interests include neural network modeling, psychology,
phenomenology, complex adaptive systems, and cognitive robotics. He is an author
of "Exploring Robotic Minds: Actions, Symbols, and Consciousness as Self-Organizing
Dynamic Phenomena." published from Oxford Univ. Press in 2016.
