I am a research scientist working at a small local startup in Okinawa, Japan. I used to work as a freelance working for a few companies and research institutes that would like to use machine learning and predictive analytics for their business and research. My specialty is deep learning and sequential decision making under uncertainty such as reinforcement learning and POMDP.

Research Interests:
  • Analysis of big data using a deep learning framework
  • Task-dependent spatiotemporal representation in a partially observable domain
  • Theoretical relationships between spiking neuron models and energy-based models
Favorite Topics:
  • Energy-based model (a.k.a. undirected graphical model, Markov random field)
  • Sequential decision making under uncertainty (reinforcement learning, POMDP, and PORL)
  • Dynamic Boltzmann Machine (DyBM)
  • Deep learning and Recurrent neural network
  • Computational neuroscience with theoretical underpinnings
  • Dynamic causal modeling (DCM) for fMRI
  • Game theory
  • Psychology and Cognitive science
  • Permaculture and User-oriented design
