Research Theme

My diverse research interests include nonlinear dynamical systems, recurrent neural networks, reinforcement learning, time-series modeling, computational neurodynamics, neurorobotics, optimization & control. Overall, I am interested in statistical machine learning as a field and in searching for novel theoretical frameworks to build adaptive intelligent systems.

Previously I was leading an IBM Research-Tokyo Far Reaching Research project on closed-loop experience building embodied robots learning framework (CLEBER). CLEBER is not only applicable to robots, but is a framework for online sequential decision making in an application independent manner.

At present, I am a Principal Scientist and the Head of Research, for the Tokyo based startup LeapMind, Inc. My research team and I are building novel technology to compress massive scale deep learning models for efficient computation on edge devices, with applications to robotics and the Internet of Things. We are pursuing both deep learning algorithm research as well as research on custom deep learning hardware using our own FPGA device.
