| Outline of Final Research Achievements |
Aiming to develop a complementary system to the conventional computer system, we attempted to construct a general stochastic information processor inspired by the stochastic property of neuronal activity. First, we expanded "constrained entropy maximization principle", which is an information processing principle obtained from an observation of cortical neural activity, so that it can be applied to general stochastic elements including a stochastic neuronal pulse generator. Second, by constructing cortical neural networks and analyzing their firing activity by using numerical simulation, we analyzed how the statistical property of the output spike sequence depends on the statistical properties of a local network structure such as the degree of bidirectional coupling and the number of triangular motifs.
