What's computational cognition? †

What is the goal of our cognition? How can it meet the goal? The computational mechanism of our cognition is of central interest in order to understand what we are. By approximating an aspect of the cognitive process, we try to understand what is human-like computation. Specifically, in this lab, I, Shohei Hidaka, am doing theoretical and empirical research on various aspects of human cognition including language learning, social interaction, and embodied cognition. My approach is based on techniques developed in various fields such as machine learning, data mining, statistical modeling, information theory, nonlinear time series analysis, and so on. Even with these powerful computational tools, however, even a tiny bit of "human computation" is still mysterious!
