Research on Extension_s Utilization in Model_s Self-learning

In this article, the author seeks after the model´s intelligentizing management in DSS (decision support system) introducing the extension theory and extension engineering methods. This article brings forward a new kind of machine-learning method - extension machine method. In this method, according to the evaluation of the model in the system utilizing extension evaluation method, the model piles up experience in the continually use and obtains the exact knowledge about decision, corrects its parameter and ameliorate the arithmetic of itself. In this way, the model achieve the aim of perfecting its capability through self-learning.
