Acquisition of Dynamics Matching in Sensory-Motor Fusion System
As sensory-motor fusion systems work faster, the system performance becomes more susceptible to constraints derived from physical and computational dynamic properties of the systems. We proposed a novel concept named "dynamics matching" which aims the maximization of the system performance by adjusting of the temporal properties (dynamics) of sensors, processors and actuators, and making them consistent with dynamics of tasks or environments under physical and computational constraints.
In this study, we proposed a model of dynamics matching problems for sensory-motor fusion systems, and built an algorithm for adaptive acquisition of dynamics matching using reinforcement learning.
Some numerical experiments of target-tracking task by an active vision using the proposed algorithm illustrated the adequate adjustment of dynamics according to various constraints, and the acquisition of rational solution in the behavior-level.
