A Study on Double Bases Cooperating Mechanism in KDD ( I )

Yang Bingru,Wang Jianxin

Strategic Study of CAE 2002, Volume 4, Issue 4,   Pages 41-51

Abstract:

This paper and paper ( Ⅱ ), aiming at the problems in the mainstream development of KDD, put forward a new academic thought that, in the knowledge discovery, the database can be restricted and deriven by the knowledge base whose structure can be in turn improved by the database. An open KDD system, KDD* , with double-base cooperating mechanism can thus be created. At the same time, the velocity, precision, and the auto-cognition of knowledge discovery can be imroved and the knowledge base is structurally equipped with the capacity of real time maintenance and to evolve by itself. This paper mainly deals with the corresponding relation between the database and knowledge base, which are the basis of double-base cooperating mechanism.

Abstract: As a wearable robot, an exoskeleton provides a direct transfer of mechanical power to assist or augment the wearer’s movement with an anthropomorphic configuration. When an exoskeleton is used to facilitate the wearer’s movement, a motion generation process often plays an important role in high-level control. One of the main challenges in this area is to generate in real time a reference trajectory that is parallel with human intention and can adapt to different situations. In this paper, we first describe a novel motion modeling method based on probabilistic (ProMP) for a , which is a new and powerful representative tool for generating motion trajectories. To adapt the trajectory to different situations when the exoskeleton is used by different wearers, we propose a novel scheme based on (BBO) PI combined with ProMP. The motion model is first learned by ProMP offline, which can generate reference trajectories for use by exoskeleton controllers online. PI is adopted to learn and update the model for online , which provides the capability of adaptation of the system and eliminates the effects of uncertainties. Simulations and experiments involving six subjects using the HEXO demonstrate the effectiveness of the proposed methods.
