Adaptation? Learning? Features of biological learning

All living organisms can learn the behavior appropriate to the environment. The learning process is, however, seems to be the convergence to the adapted behavior rather than learning. Living organisms can create the appropriate behavior through the behavior control in the environment. We so far proposed the novel learning scheme called tacit learning based on this feature of biological learning system. In this system, there is no explicit distinction between the behavior control and the adaptation. The primitive behaviors that consist of the reflex motions and the instinctive behaviors are tuned to the sophisticated behaviors adapted to the environment. We will introduce in this paper that the fundamental idea of tacit learning and show the simulation and experimental results of creating bipedal walking and the trajectories for obstacle avoidance of the mobile vehicle.
