My Research

Current topics:

• • Bounded rational strategies in the light of computational rationality

  • Reinforcement learning with bounded rational strategies

• Adaptive properties of cognitive biases

  • Modeling reasoning using probability logic, probabilistic conditionals and biconditionals

History

• • Since starting my lab at Tokyo Denki University from April 2008, I have gradually been shifting to computational cognitive science. With my students, I do machine learning, computer simulations, and psychological experiments.

  • In graduate school at Kobe University, my research was on discrete dynamical systems (cellular automata and finite automaton modeling) of internal measurement and endophysics. (PhD in March 2008)

• I graduated from the department of philosophy of science at University of Tokyo in 2002. My graduate thesis, named "Norms and self-reference" was on the rule-following paradox proposed by Saul Kripke (in his reading of Wittgenstein). It is similar to but different from Goodman's Grue-Bleen riddle of induction. Now to me facing the paradox looks at least like program induction facing infinite possibilities, looking for and failing to find the firm grounding (which has positive implications, too), and a quite dynamic (self-referential) relationship between specific examples and general rules.
