| Research Abstract |
The mechanism of human sense and behavior is a highly complicated nonlinear information processing system that is obtained by adapting to the complex environment. There are various complex phenomena. e.g.. a transition between various behavior patterns, a competitive recognition of multiple meaning, and, chaotic dynamics in biological systems, etc. In order to understand such human information processing, a research of human system, as a complex adaptation system, becomes very important. The fundamental goal of our research is to construct a measurement system of human cognitive behavior and to integrate various levels of human activity from biological level to behavioral and cognitive level, In this research, we mainly focused on the following three subjects as bases of such study :
1. Analysis of biological nonlinear dynamics.
2. Self-organized information processing.
3. Interactive measurement of human behavior.
1) The extraction and characterization methods of biological internal dynamics were investigated. Here we developed a concept of dynamic real-time characterization of biological dynamics and applied to the analysis of human blood flow dynamics. 2) The adaptive learning method for multi neural agents system was investigated. For the pulse neural network, we developed the method of spatio-temporal self-organized learning and applied to a binding of sensory information. 3) We constructed the interactive system between human and computer agent. Here we investigated how the behavior of agent influences human mental state and understanding of the agent.
Through these studies, we developed a basic framework to handle a non-explicit human information such as physiological or mental factor of human system.
