摘要
应用模糊控制思想确定变权的方法,解决新技术评价的信息的不确定问题,采用常权与变权相结合的方法,对新技术进行综合评价。本文不仅提出了新技术评价的一种有效的新方法,而且加快企业信息化的实现,并使模糊控制的理论和方法得到更广泛的应用。
Because of the quick flow of the data stream and the limitation of the memory, designing a good algorithm of data stream mining is a very difficult thing. In recent years, some algorithms of data stream mining were brought. This paper mainly describes some kinds of data stream mining based on decision tree in data classification algorithm, including traditional incremental decision tree classification, VFDT based on Hoeffding tree, adjustable VFDT（ i.e. CVFDT） and decision tree classify algorithm using ensemble technology. By analyzing and comparing, this paper summarizes the main characteristics of all kinds of algorithms which could provide help to researchers in this domain.
